CyberRota Analysis

AI-Generated

The Apache Airflow FAB provider is vulnerable due to a flaw in the Admin user-edit PATCH endpoint, which fails to invalidate existing database-backed sessions when a user's password is changed. This allows an attacker with access to the victim's session cookie to retain unauthorized access even after the password reset. Organizations using the FAB auth manager with database-backed sessions should prioritize upgrading to version 3.9.0 or later to mitigate this risk.

Original NVD Description

Apache Airflow FAB provider: changing a user's password through the Admin user-edit PATCH endpoint does not invalidate that user's existing database-backed sessions. An attacker who already holds a copy of the victim's session cookie keeps full access as that user after the password change, so the password reset does not evict them. Affects deployments using the FAB auth manager with database-backed sessions; an administrator (or the user themselves) performing a routine password change is the trigger, and no attacker interaction with the endpoint is needed. This is a second, independent route to the outcome addressed by CVE-2026-82311, which corrected an identifier comparison in the session-invalidation helper. That fix does not repair this endpoint, because the PATCH path never calls the helper at all. Deployments that applied the CVE-2026-82311 fix must also upgrade for this one. Users of apache-airflow-providers-fab are recommended to upgrade to version 3.9.0 or later, which fixes the issue.
