Technical details
The vulnerability is a SQL injection (CWE-89) in the advanced-mode datastore configuration of Okta Access Gateway. SAML assertion attribute values are interpolated directly into SQL query strings without sanitization or parameterization, then executed against the configured backend database. Exploitation requires: (1) Okta Access Gateway configured with advanced-mode database datastore using custom SQL queries referencing SAML assertion attributes, and (2) an active authentication session where the attacker can control values of referenced SAML assertion attributes. An authenticated attacker can inject SQL commands to read, modify, or delete data in the backend database. The vulnerability is resolved in version 2026.9.1 and later.
