CVE-2026-92821: SSSD access control bypass in LDAP password expiration evaluation

CVE-2026-92821 · Severity: medium · CVSS 6.8 · Published 2026-10-06

SSSD is a system daemon that manages authentication and authorization in enterprise Linux environments. When misconfigured to check password expiration warnings before applying access restrictions, it can incorrectly allow an authenticated user with an expired password to bypass access controls. An attacker with valid credentials and an expired password could use alternative login methods (such as SSH keys) to gain unauthorized access to systems they should not be able to reach.

Technical details

A logic flaw in SSSD causes premature termination of LDAP access rule evaluation when a password expiration warning is encountered, returning success instead of continuing to evaluate restrictive access rules. The vulnerability requires a specific non-default configuration (pwd_expire_policy_warn ordered before restrictive rules in ldap_access_order) combined with an authenticated user account possessing an expired password. An attacker with such credentials can bypass host or filter restrictions using alternative authentication methods like SSH public key authentication.
