No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

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.

No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.

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.
