Anyone able to write to the Celery broker could enqueue a forged callback and execute arbitrary code on every CeleryExecutor worker, without Airflow credentials. Deployments using the CeleryExecutor are affected.\n\nUsers are advised to upgrade to apache-airflow 3.4.0 or later, in which the worker claims the callback through the Execution API, validating the token, before running it.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-306"],"vendors":[],"products":[],"references":[{"url":"https://github.com/apache/airflow/pull/71192","tags":[]},{"url":"https://lists.apache.org/thread.html/7t514l87nhjworv2ns22b8ltxr1f7rhg","tags":[]},{"url":"https://www.cve.org/CVERecord?id=CVE-2020-11981","tags":[]}],"exploitRefs":[{"url":"https://github.com/apache/airflow/pull/71192","tags":[]}],"hasPoc":true,"ai":null}
