Summary

Docker Buildx Bake does not request the expected fs.read approval for certain filesystem inputs. An untrusted Bake definition can expose a readable file through a pathless secret whose ID is interpreted as a client-side pathname, or consume a local OCI image layout outside the project after entitlement validation checks a different path representation.

Risk Assessment

Users running untrusted Bake definitions may expose local files or OCI images to unauthorized access, leading to information disclosure.

Recommendation

Update Docker Buildx to a version containing the fix and avoid running untrusted Bake definitions.
