CVE-2020-11982: Apache Airflow

Critical severity, CVSS 9.8. EPSS: 7.2% chance of exploitation in the next 30 days.

An issue was found in Apache Airflow versions 1.10.10 and below. When using CeleryExecutor, if an attack can connect to the broker (Redis, RabbitMQ) directly, it was possible to insert a malicious payload directly to the broker which could lead to a deserialization attack (and thus remote code execution) on the Worker.

Affected products

• Apache Airflow: up to and including 1.10.10
