CVE-2026-94404Network attack vector

Unauthorized attribute modification via CSRF-exempt editField

Published Sep 21, 2026 · Updated Sep 21, 2026

Cross-site request forgery in MISP before 2.5.47 allows remote attackers to modify threat-intelligence attributes through a user's session. AttributesController::editField was placed in unlockedActions, causing the Security component to skip CSRF validation on cross-site form posts carrying the victim's session cookie. Exploitation requires an authenticated user to visit an attacker-controlled page and permits changes to attribute values, types, categories, comments, distribution settings, and timestamps.
