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.","epss":{"date":"2026-11-05","percentile":0.07663,"score":0.0018},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2479483"}],"kev":null,"metrics":[{"score":5.4,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1793929444856,"publishedAt":1790092200863,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-90462"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2479483"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2479483"}],"remediation":[{"kind":"workaround","source":"CNA: redhat","text":"There's no available mitigation for this issue."}],"revision":"997f130057e09a5150413ecbe4070f4efb7c7ed655a89315d98c2e088242cd98","sources":[{"modifiedAt":1793929444856,"name":"CNA: redhat","retrievedAt":1793931074102,"url":"https://www.cve.org/CVERecord?id=CVE-2026-90462"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793931087012,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-90462"}],"ssvc":{"assessedAt":1790097845615,"automatable":"no","exploitation":"poc","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Sssd: sssd: fail-open in ldap ppolicy access check allows continued authorization","updatedAt":1793931087012}
