Detailsinfo

A vulnerability was found in Apache Airflow up to 0.4.0. It has been rated as critical. Affected by this issue is an unknown code of the component Git Provider. The manipulation with an unknown input leads to a channel accessible vulnerability. Using CWE to declare the problem leads to CWE-300. The product does not adequately verify the identity of actors at both ends of a communication channel, or does not adequately ensure the integrity of the channel, in a way that allows the channel to be accessed or influenced by an actor that is not an endpoint. Impacted is confidentiality, integrity, and availability. CVE summarizes:

The Apache Airflow Git provider runs its git-over-SSH operations with `StrictHostKeyChecking=no` by default, disabling SSH host-key verification. An attacker who can intercept the network path between an Airflow worker and the Git server can impersonate the server (man-in-the-middle), capturing the SSH deploy key or injecting malicious repository content. Deployments that use the Git DAG bundle or Git provider to clone over SSH with a deploy key are affected. The fix changes the default to verify host keys; upgrade to apache-airflow-providers-git `0.4.1` or later and configure a `known_hosts` file.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-58065 since 06/28/2026. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 07/13/2026). The MITRE ATT&CK project declares the attack technique as T1557.
