Authentication Source Verification Issue in Okta Access Gateway (CVE-2026-115546)

Short explanation

Okta Access Gateway prior to version 2026.10.2 does not validate the selected authentication source during sign‑on. An authenticated user with an active session can modify the authentication source parameter to generate a SAML assertion that grants access to the Admin Console.

Why does it matter?

If a legitimate user can reach the admin console, they can obtain full control and cause data leakage.

What should be done?

  • Follow Okta’s official security advisory (S0)
  • Patch status is UNKNOWN; monitor for vendor fixes
  • Restrict Admin Console access at the network level
  • Monitor for suspicious authentication source changes
