  "summary": "IBM API Connect 10.0.8.0–10.0.8.12 and 12.1.0.0–12.1.1.2 are affected when configured with a connected directory service. A remote attacker may obtain tokens for other users and assume their identities because directory-backed authentication is not fully enforced.",
  "mitigation": "Apply IBM's vendor remediation when it is available; no fixed version is recorded in the supplied advisory. Until then, restrict network access to API Connect and review or revoke potentially exposed user tokens.",
