CVE Program bundle warning
The CVE Program recognizes that this CVE Record provides vulnerability information that a Supplier CNA believes is very important to consumers. The CVE Program has flagged this CVE Record as it assigns a single CVE ID to a collection of individual vulnerabilities which does not align with CVE's "one vulnerability, one ID" principle, and therefore provides incomplete information. For further clarification, please see the CVE Program's blog, "Preserving Vulnerability-Level Identification" linked below. Details within the CNA container below are viewable by clicking on the CNA name.

Title
MISP Correlation Authorization Bypass Exposes Restricted Event and Attribute Data
Summary
MISP contains an authorization flaw in its correlation handling during attribute searches. When a user performs an attribute search that triggers correlation lookups, the system authorized access to correlated attributes and events based on a stale distribution snapshot stored on the correlation row rather than the live event access control list.
Because the correlation row's distribution columns are a point-in-time copy that lacks a published flag, the authorization check becomes incorrect when an event is subsequently restricted (for example, its sharing group is changed or it is unpublished). As a result, an authenticated user could retrieve attributes and event details belonging to events they no longer have permission to view.
Preconditions:
- An authenticated user with at least read access to some events in the instance.
- The existence of correlations between events, at least one of which has been restricted after the correlation was created.
Impact:
- Confidentiality: exposure of attribute values and event metadata that the user is not authorized to access.
Affected versions: MISP prior to v2.5.48.

fix: [security] Check correlations against the live event ACL | a38b683420d9… |
Fix summary
The fix ensures that correlation-based lookups are authorized against the live event and attribute access control lists rather than the stale distribution snapshot on the correlation row. A new filtering step validates related event IDs against the current event ACL before returning them, and attribute queries for non-admin users now include the live ACL conditions. Additionally, Event and Object fields are stripped from returned attribute results to prevent incidental metadata leakage.
Patch summary
In DefaultCorrelationBehavior.php: (1) runGetRelatedAttributes now builds query conditions that include the live attribute ACL (buildConditions) for non-site-admin users, and ensures Event and Object are contained in the query for proper filtering; (2) after fetching related attributes, Event and Object sub-objects are unset from each result; (3) fetchRelatedEventIds now passes its results through a new __filterVisibleEventIds method that queries the Event model with createEventConditions to verify each event ID is still visible to the user; (4) the new __filterVisibleEventIds method returns the event IDs unchanged for site admins or empty lists, otherwise filters against the live event ACL.
CVSS rationale
Network vector: MISP is a web application accessible over the network. Low complexity: the attacker simply performs a normal attribute search that triggers correlations; no race condition or special setup is needed. No attack requirements: the stale correlation row exists naturally after any event restriction. Low privileges: the attacker needs an authenticated account with read access to at least one event. No user interaction: the attacker initiates the search themselves. High vulnerability-component confidentiality impact: full attribute values and event metadata of restricted events are exposed. No integrity or availability impact on the vulnerable or subsequent components.
Weakness rationale
- CWE-862 The correlation lookup path failed to enforce the current (live) authorization state of the target events and attributes. Access was granted based on a stale snapshot rather than the actual ACL, effectively missing the authorization check for restricted events.
- CWE-284 The access control decision relied on outdated data (the distribution columns copied onto the correlation row) that did not reflect the current published/sharing-group state of the event, leading to improper access control.
Attack pattern rationale
- CAPEC-114 The authorization state used for correlation lookups was incorrectly adjusted (stale) relative to the actual event ACL. An attacker with a legitimate account could exploit this misalignment to access data beyond their intended privilege scope. This is the closest CAPEC pattern; the exact mechanism is a stale authorization snapshot rather than a classic privilege-escalation primitive, so the mapping is approximate.
Assumptions to verify
- The affected version boundary (< 2.5.48) is inferred from the tag_version_boundary metadata (v2.5.48, 38 commits after fix); the exact first affected version is not stated in the patch.
- CVSS PR:L assumes the attacker needs a standard authenticated MISP account with read access to at least one event; no evidence supports a lower or higher privilege requirement.
- CAPEC-114 is the closest available pattern; the actual mechanism is a stale authorization snapshot rather than a classic privilege-escalation vector, so the mapping is approximate.
- The patch does not specify whether the vulnerability requires the event to have been restricted after correlation creation, or whether other state changes (e.g., sharing group modification) also trigger the issue; the commit message mentions 'restricted' as the primary scenario.
- No public exploit or PoC is referenced; exploitation status is assumed to be 'none'.

When a user performs an attribute search that triggers correlation lookups, the system authorized access to correlated attributes and events based on a stale distribution snapshot stored on the correlation row rather than the live event access control list.\n\nBecause the correlation row\u0027s distribution columns are a point-in-time copy that lacks a published flag, the authorization check becomes incorrect when an event is subsequently restricted (for example, its sharing group is changed or it is unpublished). As a result, an authenticated user could retrieve attributes and event details belonging to events they no longer have permission to view.\n\nPreconditions:\n\n- An authenticated user with at least read access to some events in the instance.\n\n- The existence of correlations between events, at least one of which has been restricted after the correlation was created.\n\nImpact:\n\n- Confidentiality: exposure of attribute values and event metadata that the user is not authorized to access.\n\nAffected versions: MISP prior to v2.5.48."

Title
MISP Correlation Engine Fails to Refresh When Event Distribution or Sharing Group Changes
Summary
MISP contains a defect in its event save workflow that prevents the correlation engine from recalculating correlations when an event's distribution level or sharing group is modified.
When a user edits an existing event and changes its distribution or sharing_group_id, the internal before-save hook stored the incoming (new) data rather than the previously persisted values. As a result, the after-save comparison that determines whether a correlation refresh is needed never detected the change, and stale correlations persisted.
Security impact:
- Stale correlations may continue to expose event data to users in a broader sharing group after the event has been moved to a more restrictive group, resulting in unintended information disclosure.
- Conversely, newly relevant correlations may not appear after a distribution widening, degrading the completeness of threat intelligence sharing.
Preconditions:
- An authenticated user with write access to at least one MISP event.
- The user modifies the event's distribution or sharing_group_id field.

fix: [correlation] fix correlation distribution refresh on | a23e99457b84… |
Fix summary
The fix ensures that the before-save hook retrieves the previously persisted distribution and sharing_group_id values from the database for existing events, rather than capturing the incoming (new) data. This allows the after-save logic to correctly detect when these fields have changed and trigger a correlation refresh, ensuring access boundaries on correlated data are enforced promptly.
Patch summary
In app/Model/Event.php, the beforeSave method was modified. Previously, $this->__beforeSaveData was set to the full incoming $this->data['Event'] array. The patch replaces this with: (1) initializing __beforeSaveData to null, (2) checking whether the event has an existing id (i.e., it is an update, not a create), (3) issuing a targeted database query (recursive -1, selecting only Event.distribution and Event.sharing_group_id) to fetch the currently stored values, and (4) storing those fetched values in __beforeSaveData. This ensures the after-save comparison correctly identifies distribution/sharing_group_id changes.
CVSS rationale
AV:N: MISP is a network-accessible web application. AC:L: An authenticated user simply edits an event's sharing group; no race condition or complex setup is needed. AT:N: No manipulation of a separate attack target is required. PR:L: Requires an authenticated user with write access to events. UI:N: The stale correlation persists without further user interaction. VC/VI/VA:N: The vulnerable component (the event save logic) is not directly compromised in confidentiality, integrity, or availability. SC:L: The security impact is on the broader MISP instance: users in a broader sharing group may see correlation data referencing an event that was moved to a more restrictive group, resulting in limited information disclosure. SI/SA:N: No integrity or safety impact on other systems.
Weakness rationale
- CWE-284 The core security impact is that correlation data access boundaries are not enforced when an event's sharing group or distribution changes. Stale correlations can expose event data to users who should no longer have access, constituting an improper access control failure.
- CWE-665 The root cause is that the __beforeSaveData variable was initialized with the incoming (new) data rather than the previously stored data, causing the change-detection logic in afterSave to fail. This is a classic improper initialization of a state variable used for change detection.
Attack pattern rationale
- CAPEC-114 The closest plausible CAPEC is Parameter Tampering: a user modifies the distribution or sharing_group_id parameters of an event, and the application fails to properly enforce the resulting access-control changes on correlated data. The mapping is uncertain because this is not a malicious tamper per se but a legitimate parameter modification that exposes a system defect; however, CAPEC-114 best captures the scenario where parameter changes are not properly reflected in downstream access enforcement. No more specific CAPEC for 'stale derived data after parameter change' exists in the CAPEC catalog.
Assumptions to verify
- The exact fixed version number is not specified in the patch metadata; the tag boundary indicates the fix is 47 commits after v2.5.48, but the release tag containing this commit is unknown.
- The security impact is assessed as limited information disclosure through stale correlations; the patch does not indicate a direct privilege escalation or data corruption vector.
- CAPEC-114 (Parameter Tampering) is the closest available mapping; no CAPEC specifically covers 'stale derived data after a legitimate parameter change' and the mapping is approximate.
- The assumption that the afterSave hook uses __beforeSaveData to compare old vs new distribution/sharing_group_id values is inferred from the commit message and the code change pattern; the afterSave code itself is not included in the patch.
- CVSS UI:N assumes the stale correlation data is accessible via the normal MISP UI/API without additional user interaction beyond the initial event edit.
- The Co-Authored-By line for Claude Opus 4.8 is treated as a tool credit, not a human remediation developer.

Mitigation MIT-1
Architecture and Design
Operation
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Mitigation MIT-46
Architecture and Design
Strategy: Separation of Privilege
- Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
- Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
CAPEC-19: Embedding Scripts within Scripts
An adversary leverages the capability to execute their own script by embedding it within other scripts that the target software is likely to execute due to programs' vulnerabilities that are brought on by allowing remote hosts to execute scripts.
CAPEC-441: Malicious Logic Insertion
An adversary installs or adds malicious logic (also known as malware) into a seemingly benign component of a fielded system. This logic is often hidden from the user of the system and works behind the scenes to achieve negative impacts. With the proliferation of mass digital storage and inexpensive multimedia devices, Bluetooth and 802.11 support, new attack vectors for spreading malware are emerging for things we once thought of as innocuous greeting cards, picture frames, or digital projectors. This pattern of attack focuses on systems already fielded and used in operation as opposed to systems and their components that are still under development and part of the supply chain.
CAPEC-478: Modification of Windows Service Configuration
An adversary exploits a weakness in access control to modify the execution parameters of a Windows service. The goal of this attack is to execute a malicious binary in place of an existing service.
CAPEC-479: Malicious Root Certificate
An adversary exploits a weakness in authorization and installs a new root certificate on a compromised system. Certificates are commonly used for establishing secure TLS/SSL communications within a web browser. When a user attempts to browse a website that presents a certificate that is not trusted an error message will be displayed to warn the user of the security risk. Depending on the security settings, the browser may not allow the user to establish a connection to the website. Adversaries have used this technique to avoid security warnings prompting users when compromised systems connect over HTTPS to adversary controlled web servers that spoof legitimate websites in order to collect login credentials.
CAPEC-502: Intent Spoof
An adversary, through a previously installed malicious application, issues an intent directed toward a specific trusted application's component in an attempt to achieve a variety of different objectives including modification of data, information disclosure, and data injection. Components that have been unintentionally exported and made public are subject to this type of an attack. If the component trusts the intent's action without verififcation, then the target application performs the functionality at the adversary's request, helping the adversary achieve the desired negative technical impact.
CAPEC-503: WebView Exposure
An adversary, through a malicious web page, accesses application specific functionality by leveraging interfaces registered through WebView's addJavascriptInterface API. Once an interface is registered to WebView through addJavascriptInterface, it becomes global and all pages loaded in the WebView can call this interface.
CAPEC-536: Data Injected During Configuration
An attacker with access to data files and processes on a victim's system injects malicious data into critical operational data during configuration or recalibration, causing the victim's system to perform in a suboptimal manner that benefits the adversary.
CAPEC-546: Incomplete Data Deletion in a Multi-Tenant Environment
An adversary obtains unauthorized information due to insecure or incomplete data deletion in a multi-tenant environment. If a cloud provider fails to completely delete storage and data from former cloud tenants' systems/resources, once these resources are allocated to new, potentially malicious tenants, the latter can probe the provided resources for sensitive information still there.
CAPEC-550: Install New Service
When an operating system starts, it also starts programs called services or daemons. Adversaries may install a new service which will be executed at startup (on a Windows system, by modifying the registry). The service name may be disguised by using a name from a related operating system or benign software. Services are usually run with elevated privileges.
CAPEC-551: Modify Existing Service
When an operating system starts, it also starts programs called services or daemons. Modifying existing services may break existing services or may enable services that are disabled/not commonly used.
CAPEC-552: Install Rootkit
An adversary exploits a weakness in authentication to install malware that alters the functionality and information provide by targeted operating system API calls. Often referred to as rootkits, it is often used to hide the presence of programs, files, network connections, services, drivers, and other system components.
CAPEC-556: Replace File Extension Handlers
When a file is opened, its file handler is checked to determine which program opens the file. File handlers are configuration properties of many operating systems. Applications can modify the file handler for a given file extension to call an arbitrary program when a file with the given extension is opened.
CAPEC-558: Replace Trusted Executable
An adversary exploits weaknesses in privilege management or access control to replace a trusted executable with a malicious version and enable the execution of malware when that trusted executable is called.
CAPEC-562: Modify Shared File
An adversary manipulates the files in a shared location by adding malicious programs, scripts, or exploit code to valid content. Once a user opens the shared content, the tainted content is executed.
CAPEC-563: Add Malicious File to Shared Webroot
An adversaries may add malicious content to a website through the open file share and then browse to that content with a web browser to cause the server to execute the content. The malicious content will typically run under the context and permissions of the web server process, often resulting in local system or administrative privileges depending on how the web server is configured.
CAPEC-564: Run Software at Logon
Operating system allows logon scripts to be run whenever a specific user or users logon to a system. If adversaries can access these scripts, they may insert additional code into the logon script. This code can allow them to maintain persistence or move laterally within an enclave because it is executed every time the affected user or users logon to a computer. Modifying logon scripts can effectively bypass workstation and enclave firewalls. Depending on the access configuration of the logon scripts, either local credentials or a remote administrative account may be necessary.
CAPEC-578: Disable Security Software
An adversary exploits a weakness in access control to disable security tools so that detection does not occur. This can take the form of killing processes, deleting registry keys so that tools do not start at run time, deleting log files, or other methods.
