CVE-2026-103433 PUBLISHED

Bake filesystem entitlement consent is skipped for certain secret and oci-layout definitions

Assigner: Docker
Reserved: 30.09.2026 Published: 05.10.2026 Updated: 06.10.2026

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.
