Vulnerability Snapshot
CVE-2026-63377 is rated CRITICAL — exploitation is trivial or already observed in the wild and impact is severe. Patch immediately, not on the next maintenance window.
Executive Summary
TAKO AI Agent for Okta is a local-first AI agent that helps Okta administrators query tenant data using natural language. Prior to 3.0.1-beta, POST /api/auth/setup in src/api/routers/auth.py allows an unauthenticated network attacker to create the first administrator account before the legitimate owner completes initial setup. The initial_setup function checks only the is_setup completion flag and requires no authentication, one-time bootstrap token, or network restriction. The default docker-compose.yml publishes port 8001 on all interfaces, the Dockerfile starts the listener on 0.0.0.0, and src/api/main.py mounts the authentication router without a global authentication guard. The endpoint invokes create_auth_user with UserRole.ADMIN and set_auth_cookie, issuing a valid fctr_session JWT cookie. Localhost-only CORS rules do not restrict non-browser HTTP clients, and the setup operation does not require access to a real Okta tenant. The attacker becomes the sole a

Am I affected?
Affected technology is listed in the Affected Products section above. If your asset inventory contains any of them, assume in-scope until you can prove otherwise.
How urgent is the response?
Critical: do not wait for your normal patch cycle. Verify exposure today, apply the vendor patch immediately, and add detection rules for any post-exploit indicators.
How do I remediate?
Apply the vendor patch listed in the upstream advisory linked under Sources. If the patch is not yet available, follow the vendor-supplied workaround (often a config flag or feature disable) and add detections for the published exploit pattern in your SIEM. Re-scan after the patch lands to confirm the finding clears.
Where can I track exploitation activity?
