CVE-2026-78579 PUBLISHED

Improper Input Sanitization in Okta Access Gateway LDAP Datastore Filter Interpolation

Assigner: Okta
Reserved: 24.08.2026 Published: 08.09.2026 Updated: 08.09.2026

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.
