CVE-2026-72700: Getgrav Grav

High severity, CVSS 7.5. EPSS: 0.4% chance of exploitation in the next 30 days.

The getgrav/grav-plugin-login Composer plugin before 3.9.1 (used by Grav) compares password reset and account activation tokens using a non-constant-time === string comparison instead of hash_equals() in classes/Controller.php (taskReset()) and login.php (activation handler). Because the token-submission endpoint (taskReset) also lacks rate limiting, an attacker could in principle send repeated token guesses against a known username and use the timing differences to attempt to recover a valid token, though the vendor rates the practical exploitability as low and no end-to-end network exploit has been demonstrated.

Affected products
