Title
MISP mass assignment vulnerabilities allow unauthorized modification of ownership and delegation records
Summary
MISP contained multiple mass assignment vulnerabilities in the handling of collections, tag collections, event delegations, and shadow attributes. Several controller actions accepted user-supplied fields that should have remained server-controlled, including record identifiers and ownership-related fields such as id, org_id, orgc_id, and user_id. An authenticated attacker with access to the affected endpoints could craft requests containing protected fields in order to alter object ownership, redirect an update to another record, overwrite existing event delegation requests, or modify shadow attribute proposals belonging to another organization. This could result in unauthorized modification of MISP objects and, depending on object visibility and sharing configuration, unauthorized access to or transfer of sensitive threat intelligence data. The issue was fixed by explicitly pinning ownership and identity fields to their stored values during edit operations and by removing user-supplied primary keys from create-only save paths. Affected components: * CollectionsController::edit() * EventDelegationsController::delegateEvent() * ShadowAttributesController::edit() * TagCollectionsController::edit()915 * TagCollectionsController::editWithTags() Attack requirements: The attacker must be authenticated and able to reach the affected MISP endpoints. No user interaction is required.

Title
MISP sharing group creation mass assignment allows unauthorized takeover of existing sharing groups
Summary
A mass assignment vulnerability exists in MISP’s sharing group creation endpoint. When creating a new sharing group, the controller did not remove a user-supplied id field before saving the submitted data. In CakePHP, supplying a primary key in the save data can cause a create() followed by save() operation to update an existing record instead of creating a new one. An authenticated user with permission to add sharing groups could therefore submit the identifier of an existing sharing group and modify that sharing group without passing the normal edit access-control checks. This may allow the attacker to take over or alter sharing groups they do not otherwise have access to, potentially affecting the confidentiality and integrity of information shared through those groups. Affected component: app/Controller/SharingGroupsController.php, add() action

CVE-2026-54357 (GCVE-0-2026-54357)

Vulnerability from cvelistv5 – Published: 2026-06-12 19:25 – Updated: 2026-06-12 20:05
VLAI
Title
MISP improper authorization allows organization administrators to modify site administrator user settings
Summary
An improper authorization vulnerability in MISP allowed an authenticated organization administrator to access or modify user settings belonging to site administrator accounts within the same organization. The affected access-control checks scoped administrative actions by organization membership but did not exclude higher-privileged site administrator users. As a result, an organization administrator could potentially view or alter site administrator user settings and related login profile information, crossing the intended privilege boundary between organization administration and site-wide administration. The patch hardens the ACL logic by excluding site administrator accounts from organization administrator–managed user sets, adding explicit authorization failure when a target user is not administrable, and ensuring user setting and login profile operations fail closed.

Title
Daytona: Cross-org IDOR in organization role update/delete — any org owner can rewrite or destroy another org's roles
Summary
Daytona is a secure and elastic infrastructure runtime for AI-generated code execution and agent workflows. Prior to 0.185.0, Daytona's organization role update and delete endpoints authorized the caller as an owner of the organization named in the request path, but resolved and mutated the target role by its identifier alone, without verifying the role belonged to that organization. An authenticated user who owns any organization (organizations are self-service) could therefore modify the permissions of, or delete, a role belonging to a different organization, given that role's identifier. This vulnerability is fixed in 0.185.0.

CVE-2026-54258 (GCVE-0-2026-54258)

Vulnerability from cvelistv5 – Published: 2026-09-11 21:31 – Updated: 2026-09-15 16:50

Title
Cross-monitor event media authorization bypass in direct event media endpoints
Summary
ZoneMinder is a free, open source closed-circuit television software application. Versions prior to 1.36.39, 1.38.4, and 1.39.11 allow an authenticated low-privileged user with coarse `Events=View` and/or `Snapshots=View` permissions to directly fetch media for events belonging to monitors they are not allowed to access. The normal UI correctly hides the restricted monitor and its events, but direct event media views accept an arbitrary `eid` and stream media from the event path without enforcing the event/monitor-level ACL. This exposes private surveillance footage across monitor boundaries. Versions 1.36.39, 1.38.4, and 1.39.11 fix the issue.

Title
Winter: Authenticated IDOR in backend FileUpload widget allows cross-user access to attachment metadata
Summary
Winter CMS is a content management system built on the Laravel PHP framework. In versions up to and including 1.2.12, the backend FileUpload form widget trusted an attacker-controlled file_id POST parameter when resolving the attachment it operates on, allowing an authenticated backend user to read and modify attachment records belonging to other users or records. The widget's getFileRecord() lookup resolved the posted id against the global system_files table without verifying that the file belonged to the widget's own relation, parent record, or deferred-binding session. Because all attachments share a single File model and table and attachment ids are sequential integers that are easily enumerated, a user reaching any form with a fileupload field, including the built-in My Account avatar field that requires no specific permission, could target arbitrary attachments to modify their title and description via onSaveAttachmentConfig and change their sort order via onSortAttachments, which passed posted ids straight to an unscoped update. CSRF tokens remain enforced, so exploitation requires a valid authenticated backend session with any level of access. This issue is fixed in version 1.2.13.

CVE-2026-54239 (GCVE-0-2026-54239)

Title
FaustWP — Authentication Bypass via Initialization Vector Modification in Token Envelope
Summary
Faust.js is a headless WordPress toolkit. Prior to 1.8.11, the FaustWP WordPress plugin authenticates only the ciphertext in its token envelope and excludes the 16-byte initialization vector from the HMAC in WPE\FaustWP\Auth\encrypt() and WPE\FaustWP\Auth\decrypt() in plugins/faustwp/includes/auth/functions.php. A logged-in non-administrator who obtains an authorization code from GET /generate can modify the unauthenticated initialization vector so that CBC decryption changes the token type and user identifier while the HMAC remains valid. This can produce an access token for an Administrator and permit full WordPress REST API access, administrator-account creation, plugin installation, and arbitrary code execution. This issue is fixed in repository version 1.8.11.

CVE-2026-54180 (GCVE-0-2026-54180)

Title
backpack/crud: CRUD panel query scopes are not enforced on Update, Delete, and Reorder (cross-tenant IDOR)
Summary
backpack/crud provides Create, Read, Update & Delete (CRUD) functions for Backpack, a collection of Laravel packages that help users build custom administration panels. From 6.0.0 until 6.8.14 and 7.0.38, the Update, Delete, and Reorder operations resolve records from the unscoped model query instead of the query configured through addClause() or addBaseClause(). An authenticated user who knows or guesses an out-of-scope record primary key can therefore modify, delete, or reorder records hidden by tenant, ownership, or other row-level access-control scopes. Applications that do not rely on CRUD query clauses for authorization are not affected by this specific bypass. The fix routes all three write operations through getModelWithCrudPanelQuery(), matching the scoped list and read behavior. This issue is fixed in versions 6.8.14 and 7.0.38.

From 6.0.0 until 6.8.14 and 7.0.38, the Update, Delete, and Reorder operations resolve records from the unscoped model query instead of the query configured through addClause() or addBaseClause(). An authenticated user who knows or guesses an out-of-scope record primary key can therefore modify, delete, or reorder records hidden by tenant, ownership, or other row-level access-control scopes. Applications that do not rely on CRUD query clauses for authorization are not affected by this specific bypass. The fix routes all three write operations through getModelWithCrudPanelQuery(), matching the scoped list and read behavior. This issue is fixed in versions 6.8.14 and 7.0.38."

Mitigation
Architecture and Design

For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.

Mitigation
Architecture and Design Implementation

Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.

Mitigation
Architecture and Design

Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
