{"id":"CVE-2026-86462","published":"2026-09-16T09:17:07.090","lastModified":"2026-09-18T14:29:11.393","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.\n\nThis 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.\n\nUsers of apache-airflow-providers-fab are recommended to upgrade to version 3.9.0 or later, which fixes the issue.","cvssScore":9.1,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","cwes":["CWE-613"],"vendors":["apache"],"products":["apache-airflow-providers-fab"],"references":[{"url":"https://github.com/apache/airflow/pull/72657","tags":["Patch","Vendor Advisory"]},{"url":"https://lists.apache.org/thread/7sr4sggfv5fhhl3qgphcq0rlhg81do1s","tags":["Mailing List","Vendor Advisory"]},{"url":"https://lists.apache.org/thread/7sr4sggfv5fhhl3qgphcq0rlhg81do1s?users@airflow.apache.org","tags":["Vendor Advisory"]},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-82311","tags":["US Government Resource"]}],"exploitRefs":[{"url":"https://github.com/apache/airflow/pull/72657","tags":["Patch","Vendor Advisory"]}],"hasPoc":true,"ai":{"summary":"The flaw allows an attacker to maintain access to a user's account after their password is changed, due to the lack of session invalidation.","exploitability":"Exploitation is relatively easy as it requires an attacker to already have a session cookie of the victim's user, making it a targeted attack.","blast_radius":"The impact is limited to users of Apache Airflow FAB with database-backed sessions, but the attacker can maintain full access post-password change.","remediation":"Upgrade to apache-airflow-providers-fab version 3.9.0 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["auth-bypass","web","airflow","session"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-29T09:09:09.400Z"}}
