phpMyAdmin through 5.2.3 Two-Factor Authentication Removal via /config/set

Published Oct 30, 2026 CVSS 4.0 · 5.3 Medium EPSS < 1% KEV · Not listed
Description
phpMyAdmin through 5.2.3 contains a missing re-authentication vulnerability that allows authenticated attackers to remove two-factor authentication by posting the 2fa key to /config/set. Attackers holding a hijacked session can submit key=2fa with a null JSON value to SetConfigController, stripping 2FA so later logins require only the MySQL password.
