CVE-2026-75919
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.
Does this matter?
Lower severity and a low EPSS score (0.46%). Track it; it rarely justifies an emergency change on its own.
