Details

As written in the advisory (Markdown source, shown as plain text).

### Summary If directory listings are enabled for a directory that an untrusted user has upload privileges for, a malicious file name like `<img src=x onerror=alert(1)>.txt` will allow JavaScript code execution in the context of the web server’s domain. ### Details SWS generally does not perform escaping of HTML entities on any values inserted in the directory listing. At the very least `file_name` and `current_path` could contain malicious data however. `file_uri` could also be malicious but the relevant scenarios seem to be all caught by hyper. ### Impact For any web server that allow users to upload files or create directories under a name of their choosing this becomes a stored XSS vulnerability.
