CVE-2026-78560

MediumCVSS 4.8
Published: Updated: Translated: NVD NIST

Summary

The Okta Access Gateway includes an optional pass-through authentication source that accepts user identity from a client-supplied HTTP header without cryptographic validation. In architectures where this optional source is enabled without an upstream reverse proxy or firewall configured to sanitize and enforce client headers, an unauthenticated user can supply an arbitrary identity value to initiate a session.

Risk Assessment

Risk of unauthorized system access by impersonating any user, potentially leading to confidentiality and integrity breaches.

Recommendation

Update Okta Access Gateway to a patched version and configure a reverse proxy or firewall to strip or validate client headers before they reach the gateway.
