Name of the Vulnerable Software and Affected Versions Salvo versions prior to 0.88.1

Description Salvo is a Rust web backend framework. The list html function generates a file view of a folder without sanitizing file or folder names. This can lead to Cross-Site Scripting (XSS) if a website allows access to public files and anyone can upload files. The issue is exploitable through file uploads with malicious names.

Recommendations Versions prior to 0.88.1 should be updated to version 0.88.1 or later.
