In Moby prior to 20.10.20, a container build can leak any path on the host into the container. Versions of Git where CVE-2022-39253 is present and exploited by a malicious repository, when used in combination with Moby, are subject to an unexpected inclusion of arbitrary filesystem paths in the build context, without any visible warning to the user. As this issue cannot be triggered remotely, except by users who already have full control over the daemon through the API, and it requires exploiting a vulnerability in Git by convincing a user to build a maliciously crafted repository, the impact in Moby is considered low.
