Description

Salvo is a Rust web backend framework. Prior to version 0.88.1, the function list_html generates a file view of a folder without sanitizing the files or folders names, this may potentially lead to XSS in cases where a website allow the access to public files using this feature and anyone can upload a file. This issue has been patched in version 0.88.1.
