CVE-2024-43801 1 Jellyfin 1 Jellyfin 2024-10-01 4.6 Medium
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.
CVE-2021-29490 1 Jellyfin 1 Jellyfin 2024-08-03 5.8 Medium
Jellyfin is a free software media system that provides media from a dedicated server to end-user devices via multiple apps. Verions prior to 10.7.3 vulnerable to unauthenticated Server-Side Request Forgery (SSRF) attacks via the imageUrl parameter. This issue potentially exposes both internal and external HTTP servers or other resources available via HTTP `GET` that are visible from the Jellyfin server. The vulnerability is patched in version 10.7.3. As a workaround, disable external access to the API endpoints `/Items/*/RemoteImages/Download`, `/Items/RemoteSearch/Image` and `/Images/Remote` via reverse proxy, or limit to known-friendly IPs.
CVE-2021-21402 1 Jellyfin 1 Jellyfin 2024-08-03 7.7 High
Jellyfin is a Free Software Media System. In Jellyfin before version 10.7.1, with certain endpoints, well crafted requests will allow arbitrary file read from a Jellyfin server's file system. This issue is more prevalent when Windows is used as the host OS. Servers that are exposed to the public Internet are potentially at risk. This is fixed in version 10.7.1. As a workaround, users may be able to restrict some access by enforcing strict security permissions on their filesystem, however, it is recommended to update as soon as possible.
CVE-2022-35909 1 Jellyfin 1 Jellyfin 2024-08-03 8.8 High
In Jellyfin before 10.8, the /users endpoint has incorrect access control for admin functionality.
CVE-2022-35910 1 Jellyfin 1 Jellyfin 2024-08-03 5.4 Medium
In Jellyfin before 10.8, stored XSS allows theft of an admin access token.
CVE-2023-49096 1 Jellyfin 1 Jellyfin 2024-08-02 7.7 High
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.
CVE-2023-48702 1 Jellyfin 1 Jellyfin 2024-08-02 7.2 High
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.
CVE-2023-30626 1 Jellyfin 1 Jellyfin 2024-08-02 8.8 High
Jellyfin is a free-software media system. Versions starting with 10.8.0 and prior to 10.8.10 and prior have a directory traversal vulnerability inside the `ClientLogController`, specifically `/ClientLog/Document`. When combined with a cross-site scripting vulnerability (CVE-2023-30627), this can result in file write and arbitrary code execution. Version 10.8.10 has a patch for this issue. There are no known workarounds.
CVE-2023-30627 1 Jellyfin 1 Jellyfin 2024-08-02 9.1 Critical
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-2023-27161 1 Jellyfin 1 Jellyfin 2024-08-02 7.5 High
Jellyfin up to v10.7.7 was discovered to contain a Server-Side Request Forgery (SSRF) via the component /Repositories. This vulnerability allows attackers to access network resources and sensitive information via a crafted POST request.
CVE-2023-23636 1 Jellyfin 1 Jellyfin 2024-08-02 5.4 Medium
In Jellyfin 10.8.x through 10.8.3, the name of a playlist is vulnerable to stored XSS. This allows an attacker to steal access tokens from the localStorage of the victim.
CVE-2023-23635 1 Jellyfin 1 Jellyfin 2024-08-02 5.4 Medium
In Jellyfin 10.8.x through 10.8.3, the name of a collection is vulnerable to stored XSS. This allows an attacker to steal access tokens from the localStorage of the victim.
