Vulnerability in Zuke-Build Zuke

CVE-2026-119291

Zuke is a code-first, strongly typed build automation system for Deno. Prior to 1.4.0, @zuke/cli uses lstat to inspect scaffold names but then performs link-following reads, writes, and permission changes in zuke setup and zuke import. An attacker who supplies an untrusted cloned repository, template, or archive with a symbolic link at a scaffolded name can cause setup to overwrite a target outside the selected directory with the invoking user's permissions. The .gitignore path requires no flag, while --force permits a linked launcher target to be written and made executable; import can also read link-target content and incorporate it into the generated build file. This issue is fixed in version 1.4.0.
