Red Hat buildah/copier Go: path traversal
Medium4.5CVE-2026-79705 · Published Sep 15, 2026 · updated Sep 16, 2026
A flaw was found in the buildah/copier Go package. When used outside of Buildah by a non-root caller, a crafted tar archive containing malicious symlinks can escape the target extraction directory and create files outside the intended destination. Buildah itself uses chroot hardening and is not affected.
