Vulnerability from fkie_nvd - Published: 2025-04-15 21:16 - Updated: 2025-10-06 16:42
Severity ?
Summary
Jellyfin is an open source self hosted media server. Versions before 10.10.7 are vulnerable to argument injection in FFmpeg. This can be leveraged to possibly achieve remote code execution by anyone with credentials to a low-privileged user. This vulnerability was previously reported in CVE-2023-49096 and patched in version 10.8.13, but the patch can be bypassed. The original fix sanitizes some parameters to make injection impossible, but certain unsanitized parameters can still be used for argument injection. The same unauthenticated endpoints are vulnerable: /Videos/<itemId>/stream and /Videos/<itemId>/stream.<container>, likely alongside similar endpoints in AudioController. This argument injection can be exploited to achieve arbitrary file write, leading to possible remote code execution through the plugin system. While the unauthenticated endpoints are vulnerable, a valid itemId is required for exploitation and any authenticated attacker could easily retrieve a valid itemId to make the exploit work. This vulnerability is patched in version 10.10.7.

FKIE_CVE-2025-32012
Vulnerability from fkie_nvd - Published: 2025-04-15 20:15 - Updated: 2025-10-06 16:49
Severity ?
Summary
Jellyfin is an open source self hosted media server. In versions 10.9.0 to before 10.10.7, the /System/Restart endpoint provides administrators the ability to restart their Jellyfin server. This endpoint is intended to be admins-only, but it also authorizes requests from any device in the same local network as the Jellyfin server. Due to the method Jellyfin uses to determine the source IP of a request, an unauthenticated attacker is able to spoof their IP to appear as a LAN IP, allowing them to restart the Jellyfin server process without authentication. This means that an unauthenticated attacker could mount a denial-of-service attack on any default-configured Jellyfin server by simply sending the same spoofed request every few seconds to restart the server over and over. This method of IP spoofing also bypasses some security mechanisms, cause a denial-of-service attack, and possible bypass the admin restart requirement if combined with remote code execution. This issue is patched in version 10.10.7.

Este endpoint est\u00e1 dise\u00f1ado para uso exclusivo de administradores, pero tambi\u00e9n autoriza solicitudes desde cualquier dispositivo en la misma red local que el servidor Jellyfin. Gracias al m\u00e9todo que Jellyfin utiliza para determinar la IP de origen de una solicitud, un atacante no autenticado puede falsificar su IP para que parezca una IP de LAN, lo que le permite reiniciar el proceso del servidor Jellyfin sin autenticaci\u00f3n. Esto significa que un atacante no autenticado podr\u00eda lanzar un ataque de denegaci\u00f3n de servicio contra cualquier servidor Jellyfin con configuraci\u00f3n predeterminada simplemente enviando la misma solicitud falsificada cada pocos segundos para reiniciar el servidor una y otra vez. Este m\u00e9todo de suplantaci\u00f3n de IP tambi\u00e9n elude algunos mecanismos de seguridad, provoca un ataque de denegaci\u00f3n de servicio y, posiblemente, elude el requisito de reinicio del administrador si se combina con la ejecuci\u00f3n remota de c\u00f3digo.

Summary
Jellyfin is an open source self hosted media server. 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.

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.

Summary
Jellyfin is a system for managing and streaming media. Prior to version 10.8.13, the `/System/MediaEncoder/Path` endpoint executes an arbitrary file using `ProcessStartInfo` via the `ValidateVersion` function. A malicious administrator can setup a network share and supply a UNC path to `/System/MediaEncoder/Path` which points to an executable on the network share, causing Jellyfin server to run the executable in the local context. The endpoint was removed in version 10.8.13.

FKIE_CVE-2023-49096
Vulnerability from fkie_nvd - Published: 2023-12-06 20:15 - Updated: 2024-11-21 08:32
Severity ?

Summary
Jellyfin is a Free Software Media System for managing and streaming media. In affected versions there is an argument injection in the VideosController, specifically the `/Videos/<itemId>/stream` and `/Videos/<itemId>/stream.<container>` endpoints which are present in the current Jellyfin version. Additional endpoints in the AudioController might also be vulnerable, as they differ only slightly in execution. Those endpoints are reachable by an unauthenticated user. In order to exploit this vulnerability an unauthenticated attacker has to guess an itemId, which is a completely random GUID. It’s a very unlikely case even for a large media database with lots of items. Without an additional information leak, this vulnerability shouldn’t be directly exploitable, even if the instance is reachable from the Internet. There are a lot of query parameters that get accepted by the method. At least two of those, videoCodec and audioCodec are vulnerable to the argument injection. The values can be traced through a lot of code and might be changed in the process. However, the fallback is to always use them as-is, which means we can inject our own arguments. Those arguments land in the command line of FFmpeg. Because UseShellExecute is always set to false, we can’t simply terminate the FFmpeg command and execute our own. It should only be possible to add additional arguments to FFmpeg, which is powerful enough as it stands. There is probably a way of overwriting an arbitrary file with malicious content. This vulnerability has been addressed in version 10.8.13. Users are advised to upgrade. There are no known workarounds for this vulnerability.

"value": "Jellyfin es un sistema multimedia de software libre para gestionar y transmitir medios. En las versiones afectadas hay una inyecci\u00f3n de argumentos en VideosController, espec\u00edficamente los endpoints `/Videos//stream` y `/Videos//stream.` que est\u00e1n presentes en la versi\u00f3n actual de Jellyfin. Los endpoints adicionales en AudioController tambi\u00e9n pueden ser vulnerables, ya que difieren s\u00f3lo ligeramente en la ejecuci\u00f3n. Un usuario no autenticado puede acceder a esos endpoints. Para aprovechar esta vulnerabilidad, un atacante no autenticado debe adivinar un itemId, que es un GUID completamente aleatorio. Es un caso muy improbable incluso para una gran base de datos de medios con muchos elementos. Sin una filtraci\u00f3n de informaci\u00f3n adicional, esta vulnerabilidad no deber\u00eda ser explotable directamente, incluso si se puede acceder a la instancia desde Internet. Hay muchos par\u00e1metros de consulta que el m\u00e9todo acepta. Al menos dos de ellos, videoCodec y audioCodec, son vulnerables a la inyecci\u00f3n de argumentos. Los valores se pueden rastrear a trav\u00e9s de una gran cantidad de c\u00f3digo y pueden cambiarse en el proceso. Sin embargo, la alternativa es usarlos siempre tal como est\u00e1n, lo que significa que podemos inyectar nuestros propios argumentos. Esos argumentos llegan a la l\u00ednea de comando de FFmpeg. Debido a que UseShellExecute siempre est\u00e1 configurado en falso, no podemos simplemente terminar el comando FFmpeg y ejecutar el nuestro. S\u00f3lo deber\u00eda ser posible agregar argumentos adicionales a FFmpeg, que es lo suficientemente poderoso tal como est\u00e1. Probablemente exista una forma de sobrescribir un archivo arbitrario con contenido malicioso. Esta vulnerabilidad se ha solucionado en la versi\u00f3n 10.8.13. Se recomienda a los usuarios que actualicen. No se conocen workarounds para esta vulnerabilidad."

Summary
jellyfin-web is the web client for Jellyfin, a free-software media system. Starting in version 10.1.0 and prior to version 10.8.10, a stored cross-site scripting vulnerability in device.js can be used to make arbitrary calls to the `REST` endpoints with admin privileges. When combined with CVE-2023-30626, this results in remote code execution on the Jellyfin instance in the context of the user who's running it. This issue is patched in version 10.8.10. There are no known workarounds.

CVE-2025-31499 (GCVE-0-2025-31499)
Vulnerability from cvelistv5 – Published: 2025-04-15 20:36 – Updated: 2025-04-16 14:43
VLAI?
Title
Jellyfin Vulnerable to Argument Injection in FFmpeg
Summary
Jellyfin is an open source self hosted media server. Versions before 10.10.7 are vulnerable to argument injection in FFmpeg. This can be leveraged to possibly achieve remote code execution by anyone with credentials to a low-privileged user. This vulnerability was previously reported in CVE-2023-49096 and patched in version 10.8.13, but the patch can be bypassed. The original fix sanitizes some parameters to make injection impossible, but certain unsanitized parameters can still be used for argument injection. The same unauthenticated endpoints are vulnerable: /Videos/<itemId>/stream and /Videos/<itemId>/stream.<container>, likely alongside similar endpoints in AudioController. This argument injection can be exploited to achieve arbitrary file write, leading to possible remote code execution through the plugin system. While the unauthenticated endpoints are vulnerable, a valid itemId is required for exploitation and any authenticated attacker could easily retrieve a valid itemId to make the exploit work. This vulnerability is patched in version 10.10.7.

Title
Jellyfin Vulnerable to Denial of Service (DoS) via IP Spoofing
Summary
Jellyfin is an open source self hosted media server. In versions 10.9.0 to before 10.10.7, the /System/Restart endpoint provides administrators the ability to restart their Jellyfin server. This endpoint is intended to be admins-only, but it also authorizes requests from any device in the same local network as the Jellyfin server. Due to the method Jellyfin uses to determine the source IP of a request, an unauthenticated attacker is able to spoof their IP to appear as a LAN IP, allowing them to restart the Jellyfin server process without authentication. This means that an unauthenticated attacker could mount a denial-of-service attack on any default-configured Jellyfin server by simply sending the same spoofed request every few seconds to restart the server over and over. This method of IP spoofing also bypasses some security mechanisms, cause a denial-of-service attack, and possible bypass the admin restart requirement if combined with remote code execution. This issue is patched in version 10.10.7.

Title
Privilege escalation to admin from a low-privileged user via SVG upload in Jellyfin
Summary
Jellyfin is an open source self hosted media server. 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.

Title
Jellyfin Possible Remote Code Execution via custom FFmpeg binary
Summary
Jellyfin is a system for managing and streaming media. Prior to version 10.8.13, the `/System/MediaEncoder/Path` endpoint executes an arbitrary file using `ProcessStartInfo` via the `ValidateVersion` function. A malicious administrator can setup a network share and supply a UNC path to `/System/MediaEncoder/Path` which points to an executable on the network share, causing Jellyfin server to run the executable in the local context. The endpoint was removed in version 10.8.13.

Title
Argument Injection in FFmpeg codec parameters in Jellyfin
Summary
Jellyfin is a Free Software Media System for managing and streaming media. In affected versions there is an argument injection in the VideosController, specifically the `/Videos/<itemId>/stream` and `/Videos/<itemId>/stream.<container>` endpoints which are present in the current Jellyfin version. Additional endpoints in the AudioController might also be vulnerable, as they differ only slightly in execution. Those endpoints are reachable by an unauthenticated user. In order to exploit this vulnerability an unauthenticated attacker has to guess an itemId, which is a completely random GUID. It’s a very unlikely case even for a large media database with lots of items. Without an additional information leak, this vulnerability shouldn’t be directly exploitable, even if the instance is reachable from the Internet. There are a lot of query parameters that get accepted by the method. At least two of those, videoCodec and audioCodec are vulnerable to the argument injection. The values can be traced through a lot of code and might be changed in the process. However, the fallback is to always use them as-is, which means we can inject our own arguments. Those arguments land in the command line of FFmpeg. Because UseShellExecute is always set to false, we can’t simply terminate the FFmpeg command and execute our own. It should only be possible to add additional arguments to FFmpeg, which is powerful enough as it stands. There is probably a way of overwriting an arbitrary file with malicious content. This vulnerability has been addressed in version 10.8.13. Users are advised to upgrade. There are no known workarounds for this vulnerability.

"value": "Jellyfin is a Free Software Media System for managing and streaming media. In affected versions there is an argument injection in the VideosController, specifically the `/Videos/\u003citemId\u003e/stream` and `/Videos/\u003citemId\u003e/stream.\u003ccontainer\u003e` endpoints which are present in the current Jellyfin version. Additional endpoints in the AudioController might also be vulnerable, as they differ only slightly in execution. Those endpoints are reachable by an unauthenticated user. In order to exploit this vulnerability an unauthenticated attacker has to guess an itemId, which is a completely random GUID. It\u2019s a very unlikely case even for a large media database with lots of items. Without an additional information leak, this vulnerability shouldn\u2019t be directly exploitable, even if the instance is reachable from the Internet. There are a lot of query parameters that get accepted by the method. At least two of those, videoCodec and audioCodec are vulnerable to the argument injection. The values can be traced through a lot of code and might be changed in the process. However, the fallback is to always use them as-is, which means we can inject our own arguments. Those arguments land in the command line of FFmpeg. Because UseShellExecute is always set to false, we can\u2019t simply terminate the FFmpeg command and execute our own. It should only be possible to add additional arguments to FFmpeg, which is powerful enough as it stands. There is probably a way of overwriting an arbitrary file with malicious content. This vulnerability has been addressed in version 10.8.13. Users are advised to upgrade. There are no known workarounds for this vulnerability."

Title
Jellyfin Vulnerable to Argument Injection in FFmpeg
Summary
Jellyfin is an open source self hosted media server. Versions before 10.10.7 are vulnerable to argument injection in FFmpeg. This can be leveraged to possibly achieve remote code execution by anyone with credentials to a low-privileged user. This vulnerability was previously reported in CVE-2023-49096 and patched in version 10.8.13, but the patch can be bypassed. The original fix sanitizes some parameters to make injection impossible, but certain unsanitized parameters can still be used for argument injection. The same unauthenticated endpoints are vulnerable: /Videos/<itemId>/stream and /Videos/<itemId>/stream.<container>, likely alongside similar endpoints in AudioController. This argument injection can be exploited to achieve arbitrary file write, leading to possible remote code execution through the plugin system. While the unauthenticated endpoints are vulnerable, a valid itemId is required for exploitation and any authenticated attacker could easily retrieve a valid itemId to make the exploit work. This vulnerability is patched in version 10.10.7.

Title
Jellyfin Vulnerable to Denial of Service (DoS) via IP Spoofing
Summary
Jellyfin is an open source self hosted media server. In versions 10.9.0 to before 10.10.7, the /System/Restart endpoint provides administrators the ability to restart their Jellyfin server. This endpoint is intended to be admins-only, but it also authorizes requests from any device in the same local network as the Jellyfin server. Due to the method Jellyfin uses to determine the source IP of a request, an unauthenticated attacker is able to spoof their IP to appear as a LAN IP, allowing them to restart the Jellyfin server process without authentication. This means that an unauthenticated attacker could mount a denial-of-service attack on any default-configured Jellyfin server by simply sending the same spoofed request every few seconds to restart the server over and over. This method of IP spoofing also bypasses some security mechanisms, cause a denial-of-service attack, and possible bypass the admin restart requirement if combined with remote code execution. This issue is patched in version 10.10.7.

Title
Privilege escalation to admin from a low-privileged user via SVG upload in Jellyfin
Summary
Jellyfin is an open source self hosted media server. 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.

Title
Jellyfin Possible Remote Code Execution via custom FFmpeg binary
Summary
Jellyfin is a system for managing and streaming media. Prior to version 10.8.13, the `/System/MediaEncoder/Path` endpoint executes an arbitrary file using `ProcessStartInfo` via the `ValidateVersion` function. A malicious administrator can setup a network share and supply a UNC path to `/System/MediaEncoder/Path` which points to an executable on the network share, causing Jellyfin server to run the executable in the local context. The endpoint was removed in version 10.8.13.

Title
Argument Injection in FFmpeg codec parameters in Jellyfin
Summary
Jellyfin is a Free Software Media System for managing and streaming media. In affected versions there is an argument injection in the VideosController, specifically the `/Videos/<itemId>/stream` and `/Videos/<itemId>/stream.<container>` endpoints which are present in the current Jellyfin version. Additional endpoints in the AudioController might also be vulnerable, as they differ only slightly in execution. Those endpoints are reachable by an unauthenticated user. In order to exploit this vulnerability an unauthenticated attacker has to guess an itemId, which is a completely random GUID. It’s a very unlikely case even for a large media database with lots of items. Without an additional information leak, this vulnerability shouldn’t be directly exploitable, even if the instance is reachable from the Internet. There are a lot of query parameters that get accepted by the method. At least two of those, videoCodec and audioCodec are vulnerable to the argument injection. The values can be traced through a lot of code and might be changed in the process. However, the fallback is to always use them as-is, which means we can inject our own arguments. Those arguments land in the command line of FFmpeg. Because UseShellExecute is always set to false, we can’t simply terminate the FFmpeg command and execute our own. It should only be possible to add additional arguments to FFmpeg, which is powerful enough as it stands. There is probably a way of overwriting an arbitrary file with malicious content. This vulnerability has been addressed in version 10.8.13. Users are advised to upgrade. There are no known workarounds for this vulnerability.
