All versions of harp are vulnerable to Unauthorized File Access. If a symlink in the project's base directory points to a file outside of the directory, the file is served. This could allow an attacker to access sensitive files on the server.

Recommendation

No fix is currently available. Consider using an alternative module until a fix is made available.
