CVE-2026-104914
MISP contains an improper access control vulnerability in its attribute search and paginated attribute view endpoints.
Overview
CVE-2026-104914 is a known-severity vulnerability. It was published on October 2, 2026.
Technical description
MISP contains an improper access control vulnerability in its attribute search and paginated attribute view endpoints.
When a user queries for soft-deleted attributes (e.g., via the deleted-attributes search or the paginated attribute listing), the application returned soft-deleted attributes belonging to events owned by other organizations to any authenticated user who had visibility of the event. The event detail view correctly restricted soft-deleted attribute visibility to the owning organization and sync-permission users, but the attribute search and paginated view code paths lacked this restriction.
Preconditions:
- An authenticated MISP user with at least read access to an event owned by another organization.
- The user issues a query for deleted attributes (search or paginated view with the deleted filter).
Impact:
- Confidentiality: Soft-deleted threat intelligence attributes (e.g., IOCs, indicators, context) from other organizations are disclosed to unauthorized users.
