EPSS estimates a 0.69% chance of exploitation within 30 days, higher than 53% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of navidrome you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Navidrome is an open source web-based music collection server and streamer. A security vulnerability has been identified in navidrome's subsonic endpoint, allowing for authentication bypass. This exploit enables unauthorized access to any known account by utilizing a JSON Web Token (JWT) signed with the key "not so secret". The vulnerability can only be exploited on instances that have never been restarted. Navidrome supports an extension to the subsonic authentication scheme, where a JWT can be provided using a `jwt` query parameter instead of the traditional password or token and salt (corresponding to resp. the `p` or `t` and `s` query parameters). This authentication bypass vulnerability potentially affects all instances that don't protect the subsonic endpoint `/rest/`, which is expected to be most instances in a standard deployment, and most instances in the reverse proxy setup too (as the documentation mentions to leave that endpoint unprotected). This issue has been patched in version 0.50.2.

The underlying weakness: Improper Authentication
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
How developers prevent this class of flaw
- Use an authentication framework or library such as the OWASP ESAPI Authentication feature.
