Aug 12, 2026Seerr is an open-source media request and discovery manager for Jellyfin, Plex, and Emby.CVE-2026-73291 · Other software · seerr-team · reported by GitHubHigh 7.1
Seerr is an open-source media request and discovery manager for Jellyfin, Plex, and Emby. Prior to version 3.4.0, Seerr's ImageProxy in server/lib/imageproxy.ts uses the upstream ETag and Content-Type response headers to build a cache filename for the unauthenticated GET /avatarproxy/:jellyfinUserId route, allowing a malicious or compromised Jellyfin or Emby server, or a man-in-the-middle attacker on a plaintext media-server connection, to supply traversal sequences that path.join and fs.writeFile normalize outside the cache directory, overwrite /app/dist/index.js or other files, and execute code as the node user after a container restart. This issue is fixed in version 3.4.0.

Overseerr through 1.35.0 contains an authorization bypass through user-controlled key vulnerability in the push subscription API that allows authenticated users to list, read, and delete any other user's push subscriptions by supplying an arbitrary userId in the path parameters. Attackers can exploit the missing ownership check in the affected handlers to access target user records without the filteredFields filter, leaking sensitive data including email addresses and plexId values.

A reflected Cross-Site Scripting (XSS) vulnerability in the RaiseError function of Skrol29 TbsZip version 2.17 and earlier allows remote attackers to execute arbitrary web script or HTML via a crafted payload in a filename parameter (e.g., to the FileRead function). This occurs because the error message is not properly sanitized before being output to the user. This vulnerability is fixed in version 2.18.

Feb 27, 2026Seerr is an open-source media request and discovery manager for Jellyfin, Plex, and Emby.CVE-2026-27793 · Other software · seerr-team · reported by GitHubMedium 6.5
Seerr is an open-source media request and discovery manager for Jellyfin, Plex, and Emby. Prior to version 3.1.0, the `GET /api/v1/user/:id` endpoint returns the full settings object for any user, including Pushover, Pushbullet, and Telegram credentials, to any authenticated requester regardless of their privilege level. This vulnerability can be exploited alone or combined with the reported unauthenticated account creation vulnerability, CVE-2026-27707. When combined, the two vulnerabilities create a zero-prior-access chain that leaks third-party API credentials for all users, including administrators. Version 3.1.0 contains a fix for both this vulnerability and for CVE-2026-27707.

Feb 27, 2026Seerr is an open-source media request and discovery manager for Jellyfin, Plex, and Emby.CVE-2026-27792 · Other software · seerr-team · reported by GitHubMedium 5.4
Seerr is an open-source media request and discovery manager for Jellyfin, Plex, and Emby. A missing authorization vulnerability has been identified in the application starting in version 2.7.0 and prior to version 3.1.0. It allows authenticated users to access and modify data belonging to other users. This issue is due to the absence of the `isOwnProfileOrAdmin()` middleware on several push subscription API routes. Version 3.1.0 fixes the issue.

Feb 27, 2026Seerr is an open-source media request and discovery manager for Jellyfin, Plex, and Emby.CVE-2026-27707 · Other software · seerr-team · reported by GitHubHigh 7.3
Seerr is an open-source media request and discovery manager for Jellyfin, Plex, and Emby. Starting in version 2.0.0 and prior to version 3.1.0, an authentication guard logic flaw in `POST /api/v1/auth/jellyfin` allows an unauthenticated attacker to register a new Seerr account on any Plex-configured instance by authenticating with an attacker-controlled Jellyfin server. The attacker receives an authenticated session and can immediately use the application with default permissions, including the ability to submit media requests to Radarr/Sonarr. Any Seerr deployment where all three of the following are true may be vulnerable: `settings.main.mediaServerType` is set to `PLEX` (the most common deployment).; `settings.jellyfin.ip` is set to `""` (default, meaning Jellyfin was never configured); and `settings.main.newPlexLogin` is set to `true` (default). Jellyfin-configured and Emby-configured deployments are not affected. Version 3.1.0 of Seerr fixes this issue.

Buffer overflow in CHttpServer::OnParseError in the ISAPI extension (Isapi.cpp) when built using Microsoft Foundation Class (MFC) static libraries in Visual C++ 5.0, and 6.0 before SP3, as used in multiple products including BadBlue, allows remote attackers to cause a denial of service (access violation and crash) and possibly execute arbitrary code via a long query string that causes a parsing error.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
