The Jellyfin user profile image upload accepts SVG files, allowing for a stored XSS attack against an admin user via a specially crafted malicious SVG file. When viewed by an admin outside of the Jellyfin Web UI (e.g. via \"view image\" in a browser), this malicious SVG file could interact with the browser's LocalStorage and retrieve an AccessToken, which in turn can be used in an API call to elevate the target user to a Jellyfin administrator. The actual attack vector is unlikely to be exploited, as it requires specific actions by the administrator to view the SVG image outside of Jellyfin's WebUI, i.e. it is not a passive attack. The underlying exploit mechanism is solved by PR #12490, which forces attached images (including the potential malicious SVG) to be treated as attachments and thus downloaded by browsers, rather than viewed. This prevents exploitation of the LocalStorage of the browser. This PR has been merged and the relevant code changes are included in release version 10.9.10. All users are advised to upgrade."}, {"lang": "es", "value": "Jellyfin es un servidor multimedia alojado en un servidor propio de c\u00f3digo abierto. La carga de la imagen de perfil de usuario de Jellyfin acepta archivos SVG, lo que permite un ataque XSS almacenado contra un usuario administrador a trav\u00e9s de un archivo SVG malicioso especialmente manipulado. Cuando un administrador lo ve fuera de la interfaz web de Jellyfin (por ejemplo, a trav\u00e9s de \"ver imagen\" en un navegador), este archivo SVG malicioso podr\u00eda interactuar con el almacenamiento local del navegador y recuperar un token de acceso, que a su vez se puede utilizar en una llamada de API para elevar al usuario objetivo a un administrador de Jellyfin. Es poco probable que se explote el vector de ataque real, ya que requiere acciones espec\u00edficas por parte del administrador para ver la imagen SVG fuera de la interfaz web de Jellyfin, es decir, no es un ataque pasivo. El mecanismo de explotaci\u00f3n subyacente se resuelve con la PR #12490, que obliga a que las im\u00e1genes adjuntas (incluido el SVG potencialmente malicioso) se traten como archivos adjuntos y, por lo tanto, se descarguen por los navegadores, en lugar de verse. Esto evita la explotaci\u00f3n del almacenamiento local del navegador. Esta PR se ha fusionado y los cambios de c\u00f3digo relevantes se incluyen en la versi\u00f3n de lanzamiento 10.9.10. Se recomienda a todos los usuarios que actualicen."}], "lastModified": "2024-10-01T15:25:52.560", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:jellyfin:jellyfin:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B5EDE002-11D9-4A3B-8A2A-FE61C9BDC569", "versionEndIncluding": "10.9.10", "versionStartIncluding": "10.8.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
