`Clean` is not intended to sanitize against path traversal attacks. This function is for finding the shortest path name equivalent to the given input. Using `Clean` to sanitize file reads may expose this application to path traversal attacks, where an attacker could access arbitrary files on the server. To fix this easily, write this: `filepath.FromSlash(path.Clean("/"+strings.Trim(req.URL.Path, "/")))` However, a better solution is using the `SecureJoin` function in the package `filepath-securejoin`. See https://pkg.go.dev/github.com/cyphar/filepath-securejoin#section-readme.

path := filepath.Clean(strings.TrimPrefix(requestURI, baseURL.Path()))

RegExp() called with a `regexp` function argument, this might allow an attacker to cause a Regular Expression Denial-of-Service (ReDoS) within your application as RegExP blocks the main thread. For this reason, it is recommended to use hardcoded regexes instead. If your regex is run on user-controlled input, consider performing input validation or use a regex checking/sanitization library such as https://www.npmjs.com/package/recheck to verify that the regex does not appear vulnerable to ReDoS.

return fn !== undefined ? fn.call(regexp, O) : new RegExp(regexp)[MATCH](String(O));

The Origin header in the HTTP WebSocket handshake is used to guarantee that the connection accepted by the WebSocket is from a trusted origin domain. Failure to enforce can lead to Cross Site Request Forgery (CSRF). As per "gorilla/websocket" documentation: "A CheckOrigin function should carefully validate the request origin to prevent cross-site request forgery."
