CVE-2026-33748

ADVISORY - github

Summary

Impact

Insufficient validation of Git URL fragment subdir components (<url>#<ref>:<subdir>, docs) 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.
