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.\n\nAffects 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.\n\napache-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.\n\nUsers of apache-airflow-providers-fab are recommended to upgrade to version 3.9.0 or later, which compares the identifiers consistently."}], "lastModified": "2026-09-18T14:28:43.283", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:apache:apache-airflow-providers-fab:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "4472D53A-4461-4F51-970A-C62B4F449722", "versionEndExcluding": "3.9.0", "versionStartIncluding": "2.4.2"}], "operator": "OR"}]}], "sourceIdentifier": "security@apache.org"}
