Upgrade github.com/moby/buildkit/worker to version 0.12.5 or higher.
Overview
Affected versions of this package are vulnerable to Improper Handling of Insufficient Privileges (Leaky Vessels) via APIs for running interactive containers based on built images. It is possible to use these APIs to ask BuildKit to run a container with elevated privileges. Normally, running such containers is only allowed if special security.insecure entitlement is enabled both by buildkitd configuration and allowed by the user initializing the build request.
Workaround
Avoid using BuildKit frontends from untrusted sources. A frontend image is usually specified as the #syntax line in the Dockerfile, or with the --frontend flag when using the buildctl build command.
This vulnerability was discovered and responsibly disclosed as part of the Leaky Vessels project.
