Title
cti-transmute CSRF Allows Unauthorized Follow and Notification State Changes
Summary
Affected versions of MISP cti-transmute expose several state-changing account operations as GET requests:
*
/account/follow
*
/account/delete_notification
*
/account/mark_notification_read
*
/account/mark_all_read
These endpoints require authentication, but before the fix they could be invoked with simple GET requests. That makes them susceptible to cross-site request forgery because a third-party site can induce the victim’s browser to send authenticated GET requests automatically.
The patch converts the actions to POST or DELETE and updates the frontend to include an X-CSRFToken header, providing explicit CSRF protection for those state-changing operations.

Title
cti-transmute Conversion Table Allows XSS via Unescaped Cell Content During Search Highlighting
Summary
Affected versions of cti-transmute improperly handle conversion-table values passed through the search highlighting feature. The highlight() function previously returned the underlying text directly when no search query was supplied, or performed a regex replacement that inserted <mark> tags without first escaping the original content. Because the resulting value is used by an HTML-rendering sink, malicious markup contained in conversion data could be interpreted as HTML rather than displayed as text.
The fix introduces a shared highlightMatches() helper that first converts special characters such as <, >, &, and quotes into HTML entities. Only after escaping does the code insert the application-controlled <mark> element used for search highlighting.

Title
cti-transmute Unauthenticated SSRF via Hostnames Resolving to Internal IP Addresses
Summary
Affected versions of cti-transmute contain an SSRF vulnerability in the /fetch_misp_event and /misp_search_events endpoints.
The URL validation routine checked whether a supplied hostname was itself an IP literal and rejected private, loopback, link-local, or reserved IPs. However, ordinary domain names were accepted without resolving them first. An attacker could therefore use a hostname whose DNS record pointed to an internal address and cause the cti-transmute server to issue requests into its internal network. The commit explicitly states that anonymous callers could make the server request the internal target and read the response.
The fix resolves hostnames using socket.getaddrinfo(), checks that every resolved address is globally routable, and additionally places @login_required on both affected MISP fetch/search routes.

cti-transmute Stored XSS via Crafted Tag Icon on Admin Triage Interface
Summary
Affected versions of cti-transmute allow a tag's icon value to be stored and later interpolated into HTML through Vue's v-html. The helper mapIcon() previously constructed an HTML string directly from the icon value:
<i class="fas fa-${name}"></i>
Because the icon is user-supplied, a crafted value could break out of the intended markup and inject attacker-controlled HTML. When the affected tag was later rendered, including on the administrative triage interface, the payload could execute in the viewer's browser.
The patch mitigates the issue at multiple layers: v-html is replaced with Vue :class binding, mapIcon() now returns only a constrained FontAwesome class string, and the backend validates icons against the FontAwesome catalogue or a strict [a-z0-9-]{1,40} slug pattern before storing them.

Title
cti-transmute Saved Graph Configuration Allows Stored Cross-Site Scripting via svgIcon
Summary
Affected versions of cti-transmute insufficiently validate saved graph configuration data. Graph configurations can contain style properties that are later consumed by Pivotick, and Pivotick interprets svgIcon as HTML. Because saved configurations may be created by one user and later displayed to other users—including administrators—a malicious user could store a crafted svgIcon value that executes script in another viewer’s browser.
The fix introduces a strict configuration schema on both the server and client. Only known properties are accepted, style entries are limited to shape, color, and size, and dangerous properties such as svgIcon and iconClass are explicitly rejected. Existing stored configurations are also sanitized when listed and again before being applied in the browser.

Title
cti-transmute Remote MISP Event Browser Allows Cross-Site Scripting via Malicious Event Metadata
Summary
Affected versions of cti-transmute render data obtained from a remote MISP instance into the event-browser interface using HTML interpolation. Because fields such as event IDs, event information, organization names, tags, tag colors, TLP labels, distribution labels, and error/flash text may be controlled by the remote MISP server, a malicious or compromised remote instance could return crafted values that inject HTML or script-capable content into the cti-transmute interface.
The patch explicitly notes that remote-derived values must not reach innerHTML, and replaces string-built rows and badges with DOM nodes populated through textContent. It also restricts remote-controlled tag colors to six-digit hexadecimal values, preventing malicious CSS values such as url(...).

Title
cti-transmute Sunburst and Treemap Tooltips Allow Cross-Site Scripting via Crafted Conversion Data
Summary
Affected versions of cti-transmute fail to HTML-escape attacker-controlled values used in ECharts Sunburst and Treemap tooltip formatters. Slice names may originate directly from STIX or MISP data, including STIX types, relationship_type, pattern prefixes, and MISP category/type values. Since ECharts interprets the formatter return value as HTML, crafted values can inject markup or script-capable content into the tooltip.
An attacker who can cause malicious conversion data to be processed can therefore inject content that executes when another user views the visualization and hovers over the affected slice. The patch replaces direct interpolation with dedicated formatter functions that call escapeHtml() on p.name, p.data.value, and p.value.

Title
cti-transmute Missing Authorization Allows Reactions to Private Comments
Summary
Affected versions of cti-transmute allow authenticated users to add or remove emoji reactions on comments without first checking whether those users are authorized to view the target comment.
The vulnerable react() handler passed an attacker-controlled comment_id directly to comments_repo.toggle_reaction() after only validating that the ID existed syntactically and that the requested emoji was permitted. Because comment-level visibility was not enforced, a user who could identify the ID of a private or otherwise inaccessible comment could modify reaction state on that comment despite lacking permission to access it.
The fix retrieves the target comment, rejects missing or deleted comments, retrieves its associated conversion, and enforces access.can_see_comment(current_user, comment, conversion). Unauthorized requests now receive HTTP 403.

Title
cti-transmute Evaluation Report Exports Expose Private Comments and Author Information
Summary
Affected versions of cti-transmute fail to apply comment-level access-control rules when generating evaluation report exports. Although normal comment retrieval filters comments according to conversion visibility, comment privacy, ownership, authorship, and administrative privileges, build_evaluation_report() previously included all evaluation comments without applying those rules.
Consequently, a user who was authorized to view a conversion could export its evaluation report as Markdown or PDF and obtain private evaluation comments that should only have been visible to the conversion owner, the comment author, or an administrator. The leaked report data also contained the comment author's name. The fix passes the requesting user into the report builder and filters every evaluation comment using the shared access.can_see_comment() authorization function.

Title
cti-transmute Following List Exposes User Email Addresses to Authenticated Users
Summary
Affected versions of MISP cti-transmute disclose users' email addresses through the account following-list endpoint. When an authenticated user follows another account, get_following() includes the followed user's email field in the API response alongside their name, user ID, and follow date. Because the email address is not required for the functionality and other related user lists omit it, an authenticated attacker could systematically follow users and collect their email addresses. The fix removes user.email from the returned object.

Title
cti-transmute Conversion History Authorization Bypass Leads to Sensitive Data Disclosure After Conversion Deletion
Summary
In affected versions of MISP cti-transmute, the conversion-history details endpoint performs an incomplete authorization check. When a history record references a deleted conversion, the associated conversion lookup returns None. The previous logic only denied access when the conversion object existed and the visibility check failed. As a result, deleted conversions bypassed the authorization check and their retained history input/output could be disclosed to a user able to request the corresponding history entry. The July 22, 2026 commit changes the logic to deny access whenever the conversion is missing or the requester lacks permission

Title
cti-transmute CSRF Allows Unauthorized Follow and Notification State Changes
Summary
Affected versions of MISP cti-transmute expose several state-changing account operations as GET requests:
*
/account/follow
*
/account/delete_notification
*
/account/mark_notification_read
*
/account/mark_all_read
These endpoints require authentication, but before the fix they could be invoked with simple GET requests. That makes them susceptible to cross-site request forgery because a third-party site can induce the victim’s browser to send authenticated GET requests automatically.
The patch converts the actions to POST or DELETE and updates the frontend to include an X-CSRFToken header, providing explicit CSRF protection for those state-changing operations.

Title
cti-transmute Conversion Table Allows XSS via Unescaped Cell Content During Search Highlighting
Summary
Affected versions of cti-transmute improperly handle conversion-table values passed through the search highlighting feature. The highlight() function previously returned the underlying text directly when no search query was supplied, or performed a regex replacement that inserted <mark> tags without first escaping the original content. Because the resulting value is used by an HTML-rendering sink, malicious markup contained in conversion data could be interpreted as HTML rather than displayed as text.
The fix introduces a shared highlightMatches() helper that first converts special characters such as <, >, &, and quotes into HTML entities. Only after escaping does the code insert the application-controlled <mark> element used for search highlighting.

Title
cti-transmute Unauthenticated SSRF via Hostnames Resolving to Internal IP Addresses
Summary
Affected versions of cti-transmute contain an SSRF vulnerability in the /fetch_misp_event and /misp_search_events endpoints.
The URL validation routine checked whether a supplied hostname was itself an IP literal and rejected private, loopback, link-local, or reserved IPs. However, ordinary domain names were accepted without resolving them first. An attacker could therefore use a hostname whose DNS record pointed to an internal address and cause the cti-transmute server to issue requests into its internal network. The commit explicitly states that anonymous callers could make the server request the internal target and read the response.
The fix resolves hostnames using socket.getaddrinfo(), checks that every resolved address is globally routable, and additionally places @login_required on both affected MISP fetch/search routes.

Title
cti-transmute Stored XSS via Crafted Tag Icon on Admin Triage Interface
Summary
Affected versions of cti-transmute allow a tag's icon value to be stored and later interpolated into HTML through Vue's v-html. The helper mapIcon() previously constructed an HTML string directly from the icon value:
<i class="fas fa-${name}"></i>
Because the icon is user-supplied, a crafted value could break out of the intended markup and inject attacker-controlled HTML. When the affected tag was later rendered, including on the administrative triage interface, the payload could execute in the viewer's browser.
The patch mitigates the issue at multiple layers: v-html is replaced with Vue :class binding, mapIcon() now returns only a constrained FontAwesome class string, and the backend validates icons against the FontAwesome catalogue or a strict [a-z0-9-]{1,40} slug pattern before storing them.

Title
cti-transmute Saved Graph Configuration Allows Stored Cross-Site Scripting via svgIcon
Summary
Affected versions of cti-transmute insufficiently validate saved graph configuration data. Graph configurations can contain style properties that are later consumed by Pivotick, and Pivotick interprets svgIcon as HTML. Because saved configurations may be created by one user and later displayed to other users—including administrators—a malicious user could store a crafted svgIcon value that executes script in another viewer’s browser.
The fix introduces a strict configuration schema on both the server and client. Only known properties are accepted, style entries are limited to shape, color, and size, and dangerous properties such as svgIcon and iconClass are explicitly rejected. Existing stored configurations are also sanitized when listed and again before being applied in the browser.

Title
cti-transmute Remote MISP Event Browser Allows Cross-Site Scripting via Malicious Event Metadata
Summary
Affected versions of cti-transmute render data obtained from a remote MISP instance into the event-browser interface using HTML interpolation. Because fields such as event IDs, event information, organization names, tags, tag colors, TLP labels, distribution labels, and error/flash text may be controlled by the remote MISP server, a malicious or compromised remote instance could return crafted values that inject HTML or script-capable content into the cti-transmute interface.
The patch explicitly notes that remote-derived values must not reach innerHTML, and replaces string-built rows and badges with DOM nodes populated through textContent. It also restricts remote-controlled tag colors to six-digit hexadecimal values, preventing malicious CSS values such as url(...).

Title
cti-transmute Sunburst and Treemap Tooltips Allow Cross-Site Scripting via Crafted Conversion Data
Summary
Affected versions of cti-transmute fail to HTML-escape attacker-controlled values used in ECharts Sunburst and Treemap tooltip formatters. Slice names may originate directly from STIX or MISP data, including STIX types, relationship_type, pattern prefixes, and MISP category/type values. Since ECharts interprets the formatter return value as HTML, crafted values can inject markup or script-capable content into the tooltip.
An attacker who can cause malicious conversion data to be processed can therefore inject content that executes when another user views the visualization and hovers over the affected slice. The patch replaces direct interpolation with dedicated formatter functions that call escapeHtml() on p.name, p.data.value, and p.value.

Title
cti-transmute Missing Authorization Allows Reactions to Private Comments
Summary
Affected versions of cti-transmute allow authenticated users to add or remove emoji reactions on comments without first checking whether those users are authorized to view the target comment.
The vulnerable react() handler passed an attacker-controlled comment_id directly to comments_repo.toggle_reaction() after only validating that the ID existed syntactically and that the requested emoji was permitted. Because comment-level visibility was not enforced, a user who could identify the ID of a private or otherwise inaccessible comment could modify reaction state on that comment despite lacking permission to access it.
The fix retrieves the target comment, rejects missing or deleted comments, retrieves its associated conversion, and enforces access.can_see_comment(current_user, comment, conversion). Unauthorized requests now receive HTTP 403.

Title
cti-transmute Evaluation Report Exports Expose Private Comments and Author Information
Summary
Affected versions of cti-transmute fail to apply comment-level access-control rules when generating evaluation report exports. Although normal comment retrieval filters comments according to conversion visibility, comment privacy, ownership, authorship, and administrative privileges, build_evaluation_report() previously included all evaluation comments without applying those rules.
Consequently, a user who was authorized to view a conversion could export its evaluation report as Markdown or PDF and obtain private evaluation comments that should only have been visible to the conversion owner, the comment author, or an administrator. The leaked report data also contained the comment author's name. The fix passes the requesting user into the report builder and filters every evaluation comment using the shared access.can_see_comment() authorization function.

Title
cti-transmute Following List Exposes User Email Addresses to Authenticated Users
Summary
Affected versions of MISP cti-transmute disclose users' email addresses through the account following-list endpoint. When an authenticated user follows another account, get_following() includes the followed user's email field in the API response alongside their name, user ID, and follow date. Because the email address is not required for the functionality and other related user lists omit it, an authenticated attacker could systematically follow users and collect their email addresses. The fix removes user.email from the returned object.

Title
cti-transmute CSRF Allows Unauthorized Follow and Notification State Changes
Summary
Affected versions of MISP cti-transmute expose several state-changing account operations as GET requests:
*
/account/follow
*
/account/delete_notification
*
/account/mark_notification_read
*
/account/mark_all_read
These endpoints require authentication, but before the fix they could be invoked with simple GET requests. That makes them susceptible to cross-site request forgery because a third-party site can induce the victim’s browser to send authenticated GET requests automatically.
The patch converts the actions to POST or DELETE and updates the frontend to include an X-CSRFToken header, providing explicit CSRF protection for those state-changing operations.

Title
cti-transmute Conversion Table Allows XSS via Unescaped Cell Content During Search Highlighting
Summary
Affected versions of cti-transmute improperly handle conversion-table values passed through the search highlighting feature. The highlight() function previously returned the underlying text directly when no search query was supplied, or performed a regex replacement that inserted <mark> tags without first escaping the original content. Because the resulting value is used by an HTML-rendering sink, malicious markup contained in conversion data could be interpreted as HTML rather than displayed as text.
The fix introduces a shared highlightMatches() helper that first converts special characters such as <, >, &, and quotes into HTML entities. Only after escaping does the code insert the application-controlled <mark> element used for search highlighting.

Title
cti-transmute Unauthenticated SSRF via Hostnames Resolving to Internal IP Addresses
Summary
Affected versions of cti-transmute contain an SSRF vulnerability in the /fetch_misp_event and /misp_search_events endpoints.
The URL validation routine checked whether a supplied hostname was itself an IP literal and rejected private, loopback, link-local, or reserved IPs. However, ordinary domain names were accepted without resolving them first. An attacker could therefore use a hostname whose DNS record pointed to an internal address and cause the cti-transmute server to issue requests into its internal network. The commit explicitly states that anonymous callers could make the server request the internal target and read the response.
The fix resolves hostnames using socket.getaddrinfo(), checks that every resolved address is globally routable, and additionally places @login_required on both affected MISP fetch/search routes.

Title
cti-transmute Stored XSS via Crafted Tag Icon on Admin Triage Interface
Summary
Affected versions of cti-transmute allow a tag's icon value to be stored and later interpolated into HTML through Vue's v-html. The helper mapIcon() previously constructed an HTML string directly from the icon value:
<i class="fas fa-${name}"></i>
Because the icon is user-supplied, a crafted value could break out of the intended markup and inject attacker-controlled HTML. When the affected tag was later rendered, including on the administrative triage interface, the payload could execute in the viewer's browser.
The patch mitigates the issue at multiple layers: v-html is replaced with Vue :class binding, mapIcon() now returns only a constrained FontAwesome class string, and the backend validates icons against the FontAwesome catalogue or a strict [a-z0-9-]{1,40} slug pattern before storing them.

Title
cti-transmute Saved Graph Configuration Allows Stored Cross-Site Scripting via svgIcon
Summary
Affected versions of cti-transmute insufficiently validate saved graph configuration data. Graph configurations can contain style properties that are later consumed by Pivotick, and Pivotick interprets svgIcon as HTML. Because saved configurations may be created by one user and later displayed to other users—including administrators—a malicious user could store a crafted svgIcon value that executes script in another viewer’s browser.
The fix introduces a strict configuration schema on both the server and client. Only known properties are accepted, style entries are limited to shape, color, and size, and dangerous properties such as svgIcon and iconClass are explicitly rejected. Existing stored configurations are also sanitized when listed and again before being applied in the browser.

Title
cti-transmute Remote MISP Event Browser Allows Cross-Site Scripting via Malicious Event Metadata
Summary
Affected versions of cti-transmute render data obtained from a remote MISP instance into the event-browser interface using HTML interpolation. Because fields such as event IDs, event information, organization names, tags, tag colors, TLP labels, distribution labels, and error/flash text may be controlled by the remote MISP server, a malicious or compromised remote instance could return crafted values that inject HTML or script-capable content into the cti-transmute interface.
The patch explicitly notes that remote-derived values must not reach innerHTML, and replaces string-built rows and badges with DOM nodes populated through textContent. It also restricts remote-controlled tag colors to six-digit hexadecimal values, preventing malicious CSS values such as url(...).

Title
cti-transmute Sunburst and Treemap Tooltips Allow Cross-Site Scripting via Crafted Conversion Data
Summary
Affected versions of cti-transmute fail to HTML-escape attacker-controlled values used in ECharts Sunburst and Treemap tooltip formatters. Slice names may originate directly from STIX or MISP data, including STIX types, relationship_type, pattern prefixes, and MISP category/type values. Since ECharts interprets the formatter return value as HTML, crafted values can inject markup or script-capable content into the tooltip.
An attacker who can cause malicious conversion data to be processed can therefore inject content that executes when another user views the visualization and hovers over the affected slice. The patch replaces direct interpolation with dedicated formatter functions that call escapeHtml() on p.name, p.data.value, and p.value.

Title
cti-transmute Missing Authorization Allows Reactions to Private Comments
Summary
Affected versions of cti-transmute allow authenticated users to add or remove emoji reactions on comments without first checking whether those users are authorized to view the target comment.
The vulnerable react() handler passed an attacker-controlled comment_id directly to comments_repo.toggle_reaction() after only validating that the ID existed syntactically and that the requested emoji was permitted. Because comment-level visibility was not enforced, a user who could identify the ID of a private or otherwise inaccessible comment could modify reaction state on that comment despite lacking permission to access it.
The fix retrieves the target comment, rejects missing or deleted comments, retrieves its associated conversion, and enforces access.can_see_comment(current_user, comment, conversion). Unauthorized requests now receive HTTP 403.

Title
cti-transmute Evaluation Report Exports Expose Private Comments and Author Information
Summary
Affected versions of cti-transmute fail to apply comment-level access-control rules when generating evaluation report exports. Although normal comment retrieval filters comments according to conversion visibility, comment privacy, ownership, authorship, and administrative privileges, build_evaluation_report() previously included all evaluation comments without applying those rules.
Consequently, a user who was authorized to view a conversion could export its evaluation report as Markdown or PDF and obtain private evaluation comments that should only have been visible to the conversion owner, the comment author, or an administrator. The leaked report data also contained the comment author's name. The fix passes the requesting user into the report builder and filters every evaluation comment using the shared access.can_see_comment() authorization function.
