**Name of the Vulnerable Software and Affected Versions**
esm.sh versions prior to 0.0.0-20260116051925-c62ab83c589e
**Description**
esm.sh is a content delivery network for web development. Versions prior to pseudoversion 0.0.0-20260116051925-c62ab83c589e contain a path traversal issue. The issue stems from an incomplete fix where `path.Clean` normalizes a path but does not prevent absolute paths within a malicious tar file.
