Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache Airflow versions 2.4.0 up to but not including 2.9.3 are affected. An authenticated DAG author can craft the doc_md parameter so that arbitrary code runs in the scheduler context, which the Airflow security model forbids. Upgrade to Airflow 2.9.3 or later, which removes the vulnerability.

Written 5 Nov 2026.
