{"id":"CVE-2026-48726","aliases":["BIT-airflow-2026-48726","GHSA-vr7m-c6v4-8cx8","PYSEC-2026-187"],"url":"https://o3.security/vulnerability/CVE-2026-48726","summary":"Apache Airflow: revoke_token() unreachable in FabAuthManager / KeycloakAuthManager logout path","details":"A bug in Apache Airflow's auth manager logout handling left previously-issued JWT tokens valid after the user clicked logout in the UI: the logout flow for `FabAuthManager` and `KeycloakAuthManager` did not actually reach the underlying `revoke_token()` call, so the JWT remained accepted by the API server until its natural expiry. An attacker holding a previously-issued JWT for a logged-out user could continue to make authenticated API calls as that user. Affects deployments configured with `FabAuthManager` or `KeycloakAuthManager` (the bug does not affect SimpleAuthManager). This is a residual gap in the fix for CVE-2025-57735, which addressed cookie-side invalidation in PR #57992 / PR #61339 but did not cover the provider-side `revoke_token()` reachability in the FAB / Keycloak code paths. Users who already upgraded for CVE-2025-57735 should additionally upgrade to `apache-airflow` 3.2.2 or later to cover the FAB / Keycloak logout paths.","published":"2026-06-01T07:35:19.270Z","modified":"2026-08-12T03:51:14.094114077Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},"epss":{"score":0.00382,"percentile":0.31562,"asOf":"2026-08-20"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"apache-airflow","fixedVersion":"3.2.2"}],"fix":{"url":"https://github.com/apache/airflow/pull/67289","label":"apache/airflow#67289"},"references":[{"type":"WEB","url":"https://pypi.python.org"},{"type":"WEB","url":"https://www.cve.org/CVERecord?id=CVE-2025-57735"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48726.json"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/630jg4z6cjkv4m2yv2ljgmf1zhdj1vqx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48726"},{"type":"FIX","url":"https://github.com/apache/airflow/pull/67289"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:14.094114077Z"}}
