NewCVE-2026-121541 Â (opens in a new tab)How to fix?
Upgrade github.com/docker/buildx/bake to version 0.38.2 or higher.
Overview
Affected versions of this package are vulnerable to Incorrect Authorization via the EntitlementConf.Validate function in Bake. When a user builds an untrusted Bake definition with multiple targets, a target without local paths can mask paths required by another target, depending on map iteration order. The unverified paths can expose files accessible to the Buildx client without the expected fs.read approval.
Workarounds
- Run only trusted Bake definitions to prevent untrusted definitions from exploiting the filesystem entitlement validation bypass.
- Check Bake definitions before building them for suspicious paths outside trusted directories to avoid exposing files through unverified paths.
