Jellyfin · Jellyfin · CVE-2021-21402
**Name of the Vulnerable Software and Affected Versions**
Jellyfin versions prior to 10.7.1
**Description**
The issue allows arbitrary file read from a Jellyfin server's file system with well-crafted requests to certain "API Endpoints". This is more prevalent when Windows is used as the host OS. Servers exposed to the public Internet are potentially at risk.
**Recommendations**
For versions prior to 10.7.1, update to version 10.7.1 as soon as possible. As a temporary workaround, users may be able to restrict some access by enforcing strict security permissions on their filesystem.
