Vulnerability details
The vulnerability allows a remote user to obtain complete attachments belonging to unpublished FAQs, potentially disclosing confidential information.
The vulnerability exists due to missing parent-publication and visibility authorization checks in phpMyFAQ's attachment download handlers when serving attachment requests. A remote user can request attachment identifiers through index.php?action=attachment&id=<ID> or /attachment/<ID> with dlattachment permission, or potentially through enabled guest downloads, to retrieve files whose parent FAQs are inaccessible.
