CVE-2026-78623Network attack vector

SQL injection via unsanitized SAML assertion values

Published Sep 8, 2026 · Updated Sep 10, 2026

SQL injection in Okta Access Gateway before 2026.9.1 allows remote authenticated users to execute unintended SQL against backend databases. Advanced-mode datastore handling substitutes unsanitized SAML assertion attribute values directly into custom query strings before preparation. Exploitation requires an active authentication session, a custom SQL query referencing a SAML attribute, and attacker control of that attribute.
