CyberRota Analysis
AI-GeneratedApache Airflow's FAB provider is vulnerable due to a flaw in its password reset functionality, which fails to delete existing database-backed sessions when a user's password is changed. This allows an attacker who possesses the victim's session cookie to maintain access even after the password reset, undermining the security of the affected user accounts. Organizations utilizing the FAB authentication manager with database session storage should prioritize upgrading to version 3.9.0 or later to mitigate this risk effectively.

Original NVD Description
Apache Airflow FAB provider: resetting a user's password does not delete that user's existing database-backed sessions, despite documented behaviour that it does. The cleanup compares the string identifier Flask-Login stores in the session against the user's integer database identifier, so the comparison never matches and no session is removed. An attacker who already holds a copy of the victim's session cookie keeps access as that user after the password change, so the reset does not evict them. Affects deployments using the FAB auth manager with `[fab] session_backend=database`. The trigger is an administrator (or the user) running the supported password-reset command as a containment action after a session cookie has been compromised; the secure-cookie backend is out of scope, as it documents that it cannot centrally delete sessions. apache-airflow-providers-fab 3.9.0 also fixes CVE-2026-86462, a second, independent route to the same outcome via the Admin user-edit endpoint; a single upgrade closes both. Users of apache-airflow-providers-fab are recommended to upgrade to version 3.9.0 or later, which compares the identifiers consistently.
