CyberRota Analysis
AI-GeneratedApache Airflow is vulnerable due to an insecure deserialization flaw in the XCom API endpoint, allowing authenticated users with write and read access to instantiate arbitrary classes on the server. This could lead to unauthorized actions or data exposure, making it critical for organizations using Apache Airflow to prioritize upgrading to version 3.3.1 or later to mitigate this risk. Users with the ability to manipulate XCom values should take immediate action to secure their environments.

Original NVD Description
Apache Airflow's XCom `GET /api/v2/{...}/xcomEntries/{key}?deserialize=true` endpoint passed a string-literal payload through `BaseXCom.deserialize_value` without the `_check_forbidden_xcom_keys` guard, allowing an authenticated API user with XCom write-and-read access to instantiate arbitrary `airflow.*` classes on the API server (CWE-502). An authenticated user who can write an XCom value and then read it back with `deserialize=true` triggers the unsafe instantiation. Users are advised to upgrade to apache-airflow 3.3.1 or later, which rejects reserved XCom serialization keys submitted as JSON string literals.
