BuildKit Git URL subdir component can cause access to restricted files
Quick fix
GHSA-4vrq-3vrq-g6gg — github.com/moby/buildkit: upgrade to the fixed version with the command below.
go get github.com/moby/buildkit@v0.28.1Details
### Impact Insufficient validation of Git URL fragment subdir components (`<url>#<ref>:<subdir>`, [docs](https://docs.docker.com/build/concepts/context/#url-fragments)) may allow access to files outside the checked-out Git repository root. Possible access is limited to files on the same mounted filesystem.
### Patches The issue has been fixed in version v0.28.1
### Workarounds The issue affects only builds that use Git URLs with a subpath component. Avoid building Dockerfiles from untrusted sources or using the subdir component from an untrusted Git repository where the subdir component could point to a symlink.
