Attack-Flow Graph

Executive Summary

In LinkAce versions 2.3.1 and below, the authenticated RSS feed endpoints in the FeedController class do not properly check user authorization. This means any authenticated user can access all links, lists, and tags from every user in the system, regardless of ownership or visibility settings. This flaw allows unauthorized access to other users' data. The issue is fixed in version 2.4.0.

Impact Analysis

This vulnerability can lead to unauthorized disclosure of all users' links, lists, and tags within the LinkAce system to any authenticated user. It compromises data confidentiality and privacy by allowing users to access information they should not have permission to see.

Mitigation Strategies

Upgrade LinkAce to version 2.4.0 or later, as this version fixes the authorization issue in the FeedController class. Until the upgrade, restrict authenticated user access to the RSS feed endpoints to trusted users only.
