Ampache · Ampache · CVE-2021-21399
**Name of the Vulnerable Software and Affected Versions**
Ampache versions prior to 4.4.1
**Description**
The issue allows unauthenticated access to Ampache using the subsonic API. To exploit this, an attacker must use a `username` that is not part of the site to bypass the auth checks.
**Recommendations**
For versions prior to 4.4.1, update to version 4.4.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the subsonic API until a patch is applied. Avoid using unknown or unverified `username` values in the subsonic API to minimize the risk of exploitation.
