    Title
    NewsBlur < 14.5.0 - Insecure Direct Object Reference in Social Interactions Endpoint
    Summary
    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.

    Title
    NewsBlur < 14.5.0 - Server-Side Request Forgery via add_url Endpoint
    Summary
    NewsBlur before version 14.5.0 contains a server-side request forgery vulnerability in the add_url endpoint that allows authenticated users to make arbitrary server requests to internal networks by failing to filter private IP addresses. Attackers can exploit this to access localhost services and cloud metadata endpoints, enabling internal network scanning and sensitive data exfiltration.
