Authenticated content disclosure via unchecked tool permissions
Published Jul 10, 2026 · Updated Jul 10, 2026
Access bypass in Drupal AI Agents before 1.1.4, 1.2.0 through 1.2.4, and 1.3.0 allows remote authenticated users to read content entities. When an agent tool loads a content entity, the module omits the required entity-access permission check and returns content outside the caller's authorization. Exposure requires an agent configured with the affected tool and attacker access to that agent; the advisory reports confidentiality loss without content modification.
