Apache Airflow JWT token not invalidated on logout

IdentifiersCVE-2025-57735CWE-613· Insufficient Session Expiration

Apache Airflow versions 3.0.0 before 3.2.0 contain a logout/session management flaw in which a JWT used for authentication was not invalidated when the user logged out. As a result, logout did not terminate the validity of the issued token, leaving it usable until its normal expiration. The issue is described by Apache as allowing reuse of a token if it had been intercepted. Airflow 3.2 introduced a token invalidation mechanism at logout to address this behavior.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

If an attacker obtains or intercepts a valid JWT issued to an Airflow user, that token may remain usable even after the legitimate user logs out. This can allow continued authenticated access as that user, with resulting confidentiality and integrity impact consistent with the privileges associated with the token. The provided CVSS information indicates no availability impact.

Mitigation

If you can’t patch tonight, do this now.

No specific mitigation beyond upgrading is provided in the supplied content. As an interim risk-reduction measure, organizations should minimize JWT exposure and interception opportunities and review token lifetime settings, but the authoritative remediation in the provided material is to upgrade to Airflow 3.2.0 or later.

Remediation

Patch, then assume compromise.

Upgrade Apache Airflow to version 3.2.0 or later. Apache states that Airflow 3.2 implements token invalidation at logout, which fixes the issue.
