Description

The Okta Access Gateway does not sanitize SAML assertion values before interpolating them into database queries in the advanced mode datastore configuration. The unsanitized values are substituted directly into the query string prior to preparation, resulting in unintended SQL execution against the configured backend database.

Affected product and versions

Preconditions

This applies if the following preconditions are present:

1. Okta Access Gateway is configured to use an advanced-mode database datastore with custom SQL queries referencing SAML assertion attributes.

2. An active authentication session providing the referenced SAML assertion attributes is present, with attacker-controlled values for at least one referenced attribute.

Customer Recommendations

To remediate this vulnerability, upgrade the Okta Access Gateway appliance to version 2026.9.1 or greater.

Resolution

The vulnerability is present in Okta Access Gateway appliance versions prior to 2026.9.1 and is resolved in version 2026.9.1.
