Security Advisories for Jellyfin

19. January 2023

The usd HeroLab analysts examined the multimedia application Jellyfin while conducting their security analyses.

Two cross-site scripting vulnerabilities were identified that allowed a simple user account to take over higher-privileged accounts, such as an administrator account. The vulnerabilities were reported to the vendor under the Responsible Disclosure Policy and subsequently fixed. Detailed information about these two advisories can be found here.
