CVE-2026-25917: CWE-502: Deserialization of Untrusted Data in Apache Software Foundation Apache Airflow
CVE-2026-25917 is a deserialization vulnerability in Apache Airflow that allows Dag Authors to craft XCom payloads causing the webserver to execute arbitrary code. Since Dag Authors are already highly trusted users, the severity of this issue is considered low. The vulnerability is fixed in Apache Airflow version 3. 2. 0.
AI Analysis
Technical Summary
This vulnerability (CWE-502) in Apache Airflow involves deserialization of untrusted data where Dag Authors can craft malicious XCom payloads that lead to arbitrary code execution within the webserver context. Although Dag Authors typically do not have code execution privileges in the webserver, this flaw elevates their capabilities. The issue affects versions prior to 3.2.0, and upgrading to Apache Airflow 3.2.0 addresses the vulnerability.
Potential Impact
The impact is limited to Dag Authors, who are already highly trusted users within Apache Airflow. The vulnerability allows these users to execute arbitrary code in the webserver context, which could lead to unauthorized actions within that scope. However, because the affected user role is already trusted, the overall severity is low.
Mitigation Recommendations
Users should upgrade to Apache Airflow version 3.2.0, which contains the fix for this vulnerability. No other mitigation guidance is provided or necessary as the issue is resolved in this official release.
