This high-severity CVE scores 8.6 under NVD CVSS v3. EPSS exploit probability: 0.7% (50th percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
