DescriptionGitHub Advisory

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.

AnalysisAI

Seerr versions 2.7.0 through 3.0.x contain an authorization bypass in push subscription API endpoints that allows authenticated users to read and modify other users' data due to missing permission checks. An attacker with valid credentials can exploit this to access sensitive information and alter configurations belonging to arbitrary accounts. …
