CVE-2026-72701

Grav CMS before 2.0.16 is affected by a timing side-channel vulnerability in Utils::verifyNonce(). The function uses a non-constant-time string comparison (the === operator) instead of PHP's hash_equals() when validating CSRF nonces . An attacker can measure response-time differences across multi...

EUVD-2026-65215

Grav CMS before 2.0.16 contains a timing vulnerability in Utils::verifyNonce that uses non-constant-time string comparison with the === operator instead of hashequals for CSRF nonce validation. Attackers can measure response timing differences to recover valid nonce values byte-by-byte through...

CVE-2026-72700

The getgrav/grav-plugin-login Composer plugin (used by Grav CMS ) before version 3.9.1 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...

CVE-2026-53525

A flaw was found in WeeChat, a free chat client. The relay authentication mechanism uses a non-constant-time comparison when verifying password hashes. This vulnerability allows a remote attacker to exploit subtle timing differences during the authentication process. By analyzing these timing...
