phpMyFAQ before 4.1.7 contains an authentication bypass vulnerability in SetupController that allows unauthenticated attackers to run database migrations and create configuration backups when maintenance mode is enabled. Attackers can call POST /api/setup/update-database and POST /api/setup/backup endpoints to execute database updates, disable maintenance mode, and extract database credentials from generated ZIP archives.

Exploitation public PoC (CISA Vulnrichment) · Automatable yes (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
