CVE-2026-103433: Bake filesystem entitlement consent is skipped for certain secret and oci-layout definitions

• Severity: medium (CVSS 6.9 v4.0)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-10-05 · updated 2026-10-06
• Weakness: CWE-862

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.

Affected products

• Docker Buildx: before 0.37.2 — fixed in 0.37.2

How to fix

Upgrade to a fixed version: Docker Buildx 0.37.2. Check the vendor advisory for mitigations.
