Can you explain this vulnerability to me?
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.
How can this vulnerability impact me? :
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.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:

What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, you should upgrade Seerr to version 3.1.0 or later, as this version includes the fix for the missing authorization checks.
