CVE-2026-111902: phpMyFAQ authorization bypass in FAQ access check

CVE-2026-111902 · Severity: medium · CVSS 5.3 · Published 2026-10-17

phpMyFAQ is a FAQ management system that stores content in multiple languages and controls access based on publication status and ACLs. An authorization bypass in the isFaqAccessibleForUser() function allows unauthenticated attackers to read comments and attachment metadata from unpublished or restricted FAQs by manipulating the Accept-Language header. This bypasses access controls intended to hide draft or restricted content from public users.

Technical details

The isFaqAccessibleForUser() function in the public API endpoints (comments and attachments) uses a flawed logic: it returns true if either the FAQ has no translation for the requested language OR if the FAQ is actually visible to the user. When language detection is enabled (default), a mismatched Accept-Language header causes hasTranslation() to return false, short-circuiting the disjunction and bypassing the published/ACL/date-window checks. The frontend controllers use the correct isFaqRecordVisible() function and are not vulnerable.
