## Description

NewsBlur before 14.5.0 contains a broken access control vulnerability that allows authenticated users to read private notification feeds by supplying arbitrary user_id values to the GET /social/interactions endpoint without ownership verification. Attackers can enumerate user_id values to access another user's follows, replies, and social activity without authorization.
