Name of the Vulnerable Software and Affected Versions harp versions <= 0.29.0

Description The issue allows information exposure through directory listing, enabling access to files that should be ignored according to the server rules. This is due to the harp module not properly handling URL-encoded underscore characters in file names, such as secret-folder. If the underscore is URL encoded, the server delivers the file.

Recommendations For harp versions <= 0.29.0, upgrade to version 0.40.2 or later.
