CVE-2026-15041 is a low-severity vulnerability with a CVSS 3.x base score of 3.7. The underlying weakness is classified as CWE-208.

Key facts

Description

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 information, though practical exploitation is extremely difficult due to PBKDF2 computational overhead.
