Navidrome allows SQL Injection via role parameter

Navidrome is an open source web-based music collection server and streamer. Versions 0.55.0 through 0.55.2 have a vulnerability due to improper input validation on the `role` parameter within the API endpoint `/api/artist`. Attackers can exploit this flaw to inject arbitrary SQL queries, potentially gaining unauthorized access to the backend database and compromising sensitive user information. Version 0.56.0 contains a patch for the issue.
