Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

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.
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.
