{"id":"CVE-2026-90462","published":"2026-09-22T16:18:08.137","lastModified":"2026-09-22T19:37:36.747","description":"A flaw was found in SSSD. When configured with the LDAP access provider and `ldap_access_order` including `ppolicy` or `lockout`, a fail-open condition in the LDAP ppolicy access check can occur if a user lookup returns zero results. This can incorrectly return success and cache an allow decision, permitting continued authorization for a deleted or deprovisioned user. A remote attacker with prior valid account context could exploit this to maintain access to information and potentially make limited modifications to resources that should no longer be available.","cvssScore":5.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","cwes":["CWE-280"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-90462","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2479483","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2479483","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
