Detailsinfo

A vulnerability was found in Apache Airflow 5.1.x. It has been rated as critical. This issue affects an unknown part of the component Pickle Handler. The manipulation with an unknown input leads to a deserialization vulnerability. Using CWE to declare the problem leads to CWE-502. The product deserializes untrusted data without sufficiently verifying that the resulting data will be valid. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

A user with access to the DB could craft a database entry that would result in executing code on Triggerer - which gives anyone who have access to DB the same permissions as Dag Author. Since direct DB access is not usual and recommended for Airflow, the likelihood of it making any damage is low. You should upgrade to version 6.0.0 of the provider to avoid even that risk.

The advisory is shared at lists.apache.org. The identification of this vulnerability is CVE-2025-69219. The exploitation is known to be easy. The attack may be initiated remotely. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 03/15/2026).

Upgrading to version 6.0.0 eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at EUVD (EUVD-2025-208401). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
