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 (a free chat client) versions 0.3.1 through 4.9.0 are affected by a timing side-channel in relay authentication. The relay uses non-constant-time string comparison functions (weechat_strcasecmp and strcmp ) to verify password hashes and plaintext passwords. An attacker can exploit timing ...
Coder: Login endpoint user enumeration via timing-defense placeholder in password comparison
Summary userpassword.Compare substituted a placeholder hash derived from the well-known string "hunter2" when the stored hash was empty. Submitting "hunter2" therefore matched accounts with no password hash nonexistent users and SSO-only users and a subsequent login-type check returned an HTTP 40...

CVE-2026-75589
Net::OAuth for Perl, versions before 0.33 , uses a non-constant-time comparison (Perl's eq operator) when verifying HMAC-SHA1 , HMAC-SHA256 , and PLAINTEXT signatures in its verify function. Because the comparison short-circuits on the first differing byte, response time varies with the length of...
