Summary

Docker Buildx before 0.37.2 does not request the expected fs.read approval for certain filesystem inputs in Bake. An untrusted Bake definition can expose a readable file through a pathless secret, or consume a local OCI image layout outside the project. An attacker who supplies an untrusted Bake definition needs a user to run it, and the flaw is classified as CWE-862 (Missing Authorization).

Description from the CNA

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. Users who run untrusted Bake definitions are affected.
