Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache Airflow versions before 2.11.1 are vulnerable to code injection in the web-server context through the LogTemplate table. A DAG author, who already holds substantial permissions, can manipulate the Airflow 2 database to run arbitrary code on the web server when a user views historical task information. Upgrade to Airflow 2.11.1, where the log template history functionality is disabled by default; to keep using log template history, upgrade to Airflow 3 instead.
