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...

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-2026-53525

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...

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,...

CVE-2026-53525

WeeChat Wee Enhanced Environment for Chat is a free chat client. In versions 0.3.1 through 4.9.0, the WeeChat relay authentication uses non-constant-time string comparison functions weechatstrcasecmp and strcmp to verify password hashes and plaintext passwords. An attacker can exploit timing...

CVE-2026-53525 WeeChat has Non-Constant-Time Password Hash Comparison in Relay Authentication

WeeChat Wee Enhanced Environment for Chat is a free chat client. In versions 0.3.1 through 4.9.0, the WeeChat relay authentication uses non-constant-time string comparison functions weechatstrcasecmp and strcmp to verify password hashes and plaintext passwords. An attacker can exploit timing...

UBUNTU-CVE-2026-75589

Net::OAuth versions before 0.33 for Perl check HMAC-SHA1, HMAC-SHA256 and PLAINTEXT signatures with a non-constant-time comparison in verify. Each of the three compares the signature carried in the message against the locally computed one with the eq operator, which returns as soon as the two...

CVE-2026-75589

Net::OAuth versions before 0.33 for Perl are vulnerable to a timing side-channel in the verify method. The HMAC-SHA1, HMAC-SHA256, and PLAINTEXT signature checks use Perl's eq operator, which returns as soon as a mismatch is found, causing response time to vary with the length of the matching pre...

bouncycastle: BC-JAVA: private key leakage via non-constant time comparisons

A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA core. A covert timing channel vulnerability, caused by non-constant time comparisons, risks the leakage of private keys in the FrodoKEM implementation. An unauthenticated, remote attacker can potentially exploit this timing discrepancy ...

hono: Hono - Timing Attack in basicAuth and bearerAuth Middleware

A flaw was found in Hono. This vulnerability, a timing attack, exists in the basicAuth and bearerAuth middlewares due to a non-constant-time string comparison. A remote attacker could exploit the early termination of string equality checks to infer valid credentials by precisely measuring respons...
