    CVE-2026-103433 (GCVE-0-2026-103433)

    Vulnerability from nvd – Published: 2026-10-05 21:54 – Updated: 2026-10-06 13:36
    VLAI
    Title
    Bake filesystem entitlement consent is skipped for certain secret and oci-layout definitions
    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. Users who run untrusted Bake definitions are affected.
