HIGHCVSS v3.1 7.1Vulnerability
CVE-2026-119549
Jellyfin through 12.4 contains a server-side request forgery vulnerability that lets authenticated users bypass SvgSecurityValidator by embedding gzip-compressed SVG in non-SVG image data URIs. Attackers can upload such profile images via POST /UserImage, then trigger unauthenticated rendering via GET /UserImage to fetch internal URLs, read local image files, or exhaust memory.
