Identifier: CVE-2026-63377

Known exploitation: Not listed in the CISA Known Exploited Vulnerabilities catalog at the last check.

Summary

CVE-2026-63377 affects TAKO AI Agent for Okta before 3.0.1-beta. The unauthenticated `POST /api/auth/setup` endpoint in `src/api/routers/auth.py` lets a network attacker create the first administrator account before the legitimate owner completes initial setup, because `initial_setup` checks only the `is_setup` flag. The attacker then gains a valid `fctr_session` JWT cookie and can read Okta-synced user data, API tokens, chat history and configuration, modify users and Okta integration credentials, or lock out administrators.

Mitigation

This issue is fixed in version 3.0.1-beta.
