apache-airflow-providers-apache-kafka is vulnerable to Unsafe Reflection
88
CVE Score
High
Unsafe Reflection
TL;DR
The Apache Kafka provider resolves dotted-path strings found in consumed message data by importing and calling the object they name. Message content that an external producer controls can point that dotted path at an arbitrary importable callable. Consuming such a message causes Airflow to import and invoke code the message itself selected. The fix restricts dotted-path resolution to a safe, allow-listed set of callables.
How do I fix this?
Upgrade the apache-airflow-providers-apache-kafka library to the patch version.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and consume Kafka messages whose content is not fully trusted.
