AI-suggested
Upgrade Apache Airflow to version 3.4.0 or later, where this token revocation failure issue has been fixed. No other mitigation is indicated.
Description
Apache Airflow's logout endpoint fails to properly revoke tokens on the server when revocation encounters errors, including database failures or tokens from external issuers with long identifiers. As a result, tokens remain valid after logout, allowing continued API access until token expiration. Users should upgrade to Apache Airflow 3.4.0 or later to address this issue.
