Source: CVE Database V5
Vendor/Project: Apache Software Foundation
Product: Apache Airflow

Description

Dag Authors, who normally should not be able to execute code in the webserver context could craft XCom payload causing the webserver to execute arbitrary code. Since Dag Authors are already highly trusted, severity of this issue is Low. Users are recommended to upgrade to Apache Airflow 3.2.0, which fixes the issue.

Technical Analysis

This vulnerability (CWE-502) in Apache Airflow involves deserialization of untrusted data via XCom payloads crafted by Dag Authors. The flaw allows execution of arbitrary code in the webserver context, which normally Dag Authors should not be able to do. Since Dag Authors have high privileges, the impact is significant. The vendor recommends upgrading to Apache Airflow 3.2.0 to remediate this issue. No official patch link or detailed remediation level is provided in the data, but the upgrade is the stated fix.

Potential Impact

Successful exploitation allows arbitrary code execution in the Airflow webserver context, potentially compromising confidentiality, integrity, and availability of the system. Because Dag Authors are already trusted users, the risk is somewhat mitigated by user role, but the vulnerability still poses a high impact as indicated by the CVSS score of 7.2.

Mitigation Recommendations

Users should upgrade to Apache Airflow version 3.2.0, which addresses this vulnerability. No other official remediation or temporary fixes are indicated. Patch status is not explicitly confirmed beyond the upgrade recommendation, so users should verify with the vendor advisory for the latest guidance.
