CVE-2026-103433

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

Published Oct 5, 2026 CVSS 4.0 · 6.9 Medium EPSS < 1% KEV · Not listed
Description
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.

Remediation

Vendor Workaround

Run only trusted Bake definitions until upgrading to v0.37.2 or later. Review Bake definitions for secrets without an explicit source and for local OCI layout contexts.
