Executive Summary

This vulnerability exists in Seerr, an open-source media request and discovery manager. It is a missing authorization issue found in versions starting from 2.7.0 up to but not including 3.1.0. The problem arises because certain push subscription API routes lack the necessary middleware called isOwnProfileOrAdmin(), which is supposed to restrict access. As a result, authenticated users can access and modify data that belongs to other users, which they should not be able to do.

Impact Analysis

This vulnerability can impact you by allowing authenticated users to access and change other users' data without proper authorization. This could lead to unauthorized data exposure or modification, potentially compromising user privacy and data integrity within the application.
