CVE-2026-111910: phpMyFAQ authorization bypass in attachment downloads

CVE-2026-111910 · Severity: medium · CVSS 6.5 · Published 2026-10-17

phpMyFAQ is a knowledge base management system used to organize internal documentation and FAQs with access controls. An authorization bypass in attachment downloads allows low-privileged users or anonymous visitors to retrieve files attached to restricted FAQs, potentially exposing confidential documents like HR policies or incident runbooks. The vulnerability affects versions before 4.1.9 and 4.2.0-beta, and requires either guest downloads to be enabled or a user account with attachment download privileges.

Technologies: Thorsten phpMyFAQ. Vendors: Thorsten.

How to fix

Fixed in: 4.1.9, 4.2.0-beta

Disable the records.allowDownloadsForGuests configuration flag and restrict the dlattachment privilege to trusted administrators only, until a version upgrade is possible.

Technical details

The vulnerability stems from three independent permission-check defects in attachment.php: missing handling of the -1 "all users" sentinel used elsewhere in the codebase, forced-true group permission checks in basic mode, and the allowDownloadsForGuests flag unconditionally bypassing per-record ACLs. An attacker with the dlattachment privilege or anonymous access (when guest downloads enabled) can request attachment IDs to download files from FAQs restricted to specific users, while the viewing path correctly enforces the same restrictions.
