CVE-2026-22153 is an authentication bypass vulnerability in Fortinet FortiOS affecting versions 7.6.0 through 7.6.4. The flaw impacts LDAP-backed authentication used by Agentless VPN or FSSO policy evaluation and can allow an unauthenticated attacker to bypass LDAP authentication when the remote LDAP server is configured in a specific way. The issue is classified as CWE-305, indicating a failure in the authentication design or enforcement path that permits access without successful completion of the intended authentication process. Successful exploitation could allow an attacker to satisfy authentication-dependent access controls without valid LDAP credentials under the affected deployment conditions.
