Attack vector: info-disclosure
Category: vulnerability-disclosure
Severity: High
CVE: CVE-2026-46366

### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-289f-fq7w-6q2w. This link is maintained to preserve external references. ### Original Description phpMyFAQ before 4.1.2 contains an information disclosure vulnerability in the getIdFromSolutionId() method that lacks permission filtering, allowing unauthenticated attackers to enumerate restricted FAQ entries and read their titles via the /solution_id_{id}.html endpoint. Attackers can sequentially iterate solution IDs to discover all FAQs including those restricted to specific users or groups, leaking sensitive metadata through redirect Location headers and page canonical links.
