CVE-2026-44332 Fiber: Username Enumeration via Timing Oracle in BasicAuth Default Authorizer

Fiber is an Express inspired web framework written in Go. Prior to 3.3.0, the default Authorizer function in the BasicAuth middleware in middleware/basicauth/config.go uses short-circuit evaluation that skips password hash comparison for non-existent usernames, enabling reliable remote username...

CVE-2026-44332

Fiber’s Go-based web framework vulnerability CVE-2026-44332 affects the BasicAuth middleware’s default Authorizer prior to v3.3.0. The issue arises from short-circuit evaluation in the Authorizer: for non-existent usernames, the password hash check is skipped, enabling remote username enumeration...

DEBIAN-CVE-2026-15041

A flaw was found in 389 Directory Server. The PBKDF2-SHA256 password verification function uses standard memcmp for comparing password hashes instead of a constant-time comparison function. A remote attacker could potentially use timing measurements of LDAP bind attempts to infer partial hash...
