{"id":"BIT-airflow-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.","aliases":["CVE-2026-48726","GHSA-vr7m-c6v4-8cx8","PYSEC-2026-187"],"modified":"2026-09-08T08:45:27.684397953Z","published":"2026-06-05T05:40:49.799Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:apache:airflow:*:*:*:*:*:python:*:*"]},"references":[{"type":"FIX","url":"https://github.com/apache/airflow/pull/67289"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/630jg4z6cjkv4m2yv2ljgmf1zhdj1vqx"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48726"},{"type":"ADVISORY","url":"https://www.cve.org/CVERecord?id=CVE-2025-57735"}],"affected":[{"package":{"name":"airflow","ecosystem":"Bitnami","purl":"pkg:bitnami/airflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.2.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/airflow/BIT-airflow-2026-48726.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}],"schema_version":"1.9.0"}
