CVE-2026-72701

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 before 3.9.1 used by Grav compares password reset and account activation tokens using a non-constant-time === string comparison instead of hashequals in classes/Controller.php taskReset and login.php activation handler. Because the token-submission...

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-2026-72701

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...

CVE-2026-72701 Grav CMS before 2.0.16 Timing Attack via verifyNonce

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 Grav before 3.9.1 Timing Attack via Non-Constant-Time Token Comparison

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 hashequals in classes/Controller.php taskReset and login.php activation handler. Because the token-submission...

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...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: SCTP: The comparison of MACs has been fixed to require constant-time operations. To prevent timing attacks, MACs need to be compared in constant-time. Use the appropriate helper function for this purpose...

Astra Linux – Vulnerability in Heimdal

The fix for CVE-2022-3437 involved changing the memcmp function to run in constant time, as well as providing a workaround for a compiler bug by adding comparisons of the result with the value “!= 0” to the memcmp function. When these patches were backported to the heimdal-7.7.1 and heimdal-7.8.0...

apr-util: Apache Portable Runtime Utility: Information disclosure via timing attack in password validation

A flaw was found in Apache Portable Runtime Utility apr-util. The aprpasswordvalidate function does not perform constant-time comparisons for hashes or passwords. This vulnerability allows a remote attacker to conduct a timing attack, particularly on platforms without crypt such as Windows, BeOS,...
