CVE-2026-78579

Estado: AnalizadaMedia (6.5)—

The Okta Access Gateway does not sanitize SAML assertion attribute values before interpolating them into LDAP search filters in the LDAP datastore configuration. The raw values are substituted directly into the filter string and passed to the LDAP search operation, resulting in modification of the intended query logic.
