Summary: Researchers have disclosed a flaw in Okta’s “Inline Hook” feature (CVE-2026-1002). Attackers with low-level API access can manipulate the session token *during* the authentication flow, extending the session lifetime indefinitely or escalating privileges without triggering MFA logs.
Business Impact: Identity is the new perimeter, and this flaw breaks the lock. It allows “Shadow Access” where a terminated employee or intruder can maintain access to SaaS apps (Salesforce, Slack) long after their account should have been revoked.
Why It Happened: A logic error in how the hook validates the “JSON Web Token” (JWT) signature allowed for parameter tampering.
Recommended Executive Action: Rotate all Okta API tokens immediately. Review your “Inline Hook” configurations and disable any hooks that are not strictly necessary until the patch (released today) is verified.
