CVE-2026-82310: Apache Airflow FAB provider: FAB auth manager: deactivated users retain and renew Core API JWT access
Apache Airflow FAB provider 2.0.0-3.8.x lets deactivated users keep unexpired Core API JWTs and mint replacements indefinitely.
CVE-2026-82310 affects apache-airflow-providers-fab versions 2.0.0 before 3.9.0. Deactivating a user account does not stop tokens issued before deactivation. While password authentication correctly rejects the disabled account, the Core API continues to accept an existing unexpired token naming it and lets that token mint a replacement. Severity is rated moderate.
