  "summary": "Path traversal via malicious package name in github.com/zarf-dev/zarf",
  "details": "A path traversal vulnerability in Zarf allows an attacker to write arbitrary files on the host system by providing a malicious package name in the package metadata. This occurs when Zarf generates SBOM or documentation outputs, or when creating a package, as it fails to properly sanitize the package name before using it in a file path.",
