MISP contains an improper access control vulnerability in its attribute search and paginated attribute view endpoints. (CVE-2026-104914)
MISP versions prior to 2.5.48 contain an improper access control vulnerability in the attribute search and paginated attribute view endpoints. Authenticated users with read access to events owned by other organizations could query for soft-deleted attributes and receive data that should have been restricted. This vulnerability exposes confidential soft-deleted threat intelligence attributes from other organizations to unauthorized users, potentially leaking sensitive information that was intended to be hidden.
AI Analysis
Technical Summary
MISP has an improper access control vulnerability (CVE-2026-104914) affecting its attribute search and paginated attribute view endpoints. When querying for soft-deleted attributes, the application incorrectly returns soft-deleted attributes belonging to events owned by other organizations to any authenticated user with visibility of the event. While the event detail view correctly restricts access to soft-deleted attributes, the search and paginated views lack this restriction, leading to unauthorized disclosure of sensitive intelligence. The vulnerability requires an authenticated user with at least read access to an event owned by another organization. It affects MISP versions prior to 2.5.48.
Potential Impact
Confidentiality is impacted as soft-deleted threat intelligence attributes from other organizations can be disclosed to unauthorized users. This may reveal sensitive indicators or context that the owning organization intended to keep hidden, potentially compromising the confidentiality of threat intelligence data.
Mitigation Recommendations
A fix is available in MISP version 2.5.48. Users should upgrade to version 2.5.48 or later to remediate this improper access control vulnerability. No other mitigation is indicated or required.
