Incorrect Authorization vulnerability in Drupal Advanced Content Feedback (aka admin_feedback) allows Forceful Browsing. This issue affects Advanced Content Feedback (aka admin_feedback) versions: from 0.0.0 to 2.8.0.
AnalysisAI
Incorrect authorization in the Drupal Advanced Content Feedback (admin_feedback) contributed module allows authenticated low-privilege users to perform forceful browsing, accessing restricted feedback resources without proper authorization checks. All module releases from 0.0.0 up to (but not including) 2.8.0 are affected. No public exploit code exists and no active exploitation has been identified; EPSS sits at the 4th percentile, consistent with the SSVC assessment of zero current exploitation.
Technical ContextAI
CWE-863 (Incorrect Authorization) describes a failure to enforce access controls after authentication - the module either omits authorization gate checks on certain URL paths or applies them inconsistently, enabling forceful browsing (directly navigating to nominally restricted endpoints). The affected component is a Drupal 9/10 contributed module (CPE cpe:2.3:a:drupal:advanced_content_feedback_(aka_admin_feedback):*:*:*:*:*:*:*:*) that provides inline content-feedback widgets and administrative interfaces, typically surfacing admin-only feedback dashboards. The root cause class - missing or mis-applied hook_access / access-check callbacks in Drupal's routing layer - allows a node of the content feedback system to be traversed without the expected privilege assertion.
RemediationAI
Upgrade the Advanced Content Feedback (admin_feedback) Drupal module to version 2.8.0 or later, as detailed in the Drupal security advisory SA-CONTRIB-2026-052 at https://www.drupal.org/sa-contrib-2026-052. The vendor has confirmed a patch is available. Sites unable to upgrade immediately should consider temporarily disabling the module via the Drupal Extend page (admin/modules) - this removes the attack surface entirely at the cost of losing feedback widget functionality. Alternatively, restricting access to feedback-related routes via Drupal's router or web-server-level path blocking (e.g., denying access to the module's admin paths in nginx or Apache config) can reduce exposure, though this approach requires knowledge of exact route paths and does not address the underlying authorization flaw. Disabling the module is the lower-risk interim workaround.
