## Affected

- sct overseerr: through 1.35.0

## Description

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.
