CVE-2026-56396

16th percentile - higher than 16% of all known CVEs

phpMyFAQ before 4.1.4 contains missing authorization vulnerabilities in editUser() and updateUserRights() endpoints that allow authenticated administrators to escalate privileges. Non-SuperAdmin users with edit_user permission can set is_superadmin flag or grant arbitrary rights to escalate to SuperAdmin access.

Privilege escalation by unauthorized users can lead to serious security breaches, including unauthorized access to sensitive data and administrative functions. Organizations should be aware of the risks associated with improper permission management.

It is recommended to update phpMyFAQ to version 4.1.4 or later to mitigate these authorization vulnerabilities. Additionally, a user permission audit should be conducted to ensure that only authorized administrators have access to critical functions.
