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...

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 ...

SUSE 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...

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...

Timing Attack

Overview org.springframework.security:spring-security-core is a package that provides security services for the Spring IO Platform. Affected versions of this package are vulnerable to Timing Attack via the comparison of sensitive values using standard string equality rather than constant-time...

CVE-2026-75589

A flaw was found in Net::OAuth. This vulnerability arises from a non-constant-time comparison used when verifying HMAC-SHA1, HMAC-SHA256, and PLAINTEXT signatures. A remote attacker could exploit this by timing the responses to submitted messages, allowing them to recover valid signatures or, in...

CVE-2026-44255

Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.0.0 until 4.14.6 and 5.0.0-beta2, AuthenticationManager.checkuser in framework/wazuh/rbac/orm.py performs checkpasswordhash only when the supplied username exists. A nonexistent username returns...

CVE-2026-44255

Wazuh (open-source threat prevention, detection, and response platform) is vulnerable to username enumeration via a timing side-channel in AuthenticationManager.check_user() within framework/wazuh/rbac/orm.py. The function performs an expensive bcrypt hash check only when the supplied username ex...
