What is CVE-2026-62671?

The Grav Login Plugin allows a logged-in user's session to be compromised through an inadequate validation mechanism in its login.regenerate2FASecret task. Prior to version 3.8.11, it accepted top-level GET requests without requiring validation via a nonce, Origin check, or Referer check. This vulnerability can be exploited during off-site navigation, enabling an attacker to overwrite the victim's TOTP secret and enforce a re-enrollment for two-factor authentication. The issue has been addressed in version 3.8.11.

Affected Version(s)

grav-plugin-login < 3.8.11
