Exposure of Sensitive Information to an Unauthorized Actor
The Flippy module 7.x-1.x before 7.x-1.2 for Drupal does not properly restrict access to nodes, which allows remote authenticated users with the permission to access content to read a link or alias to a restricted node.
CWE-200 - Information Exposure
An information exposure vulnerability is categorized as an information flow (IF) weakness, which can potentially allow unauthorized access to otherwise classified information in the application, such as confidential personal information (demographics, financials, health records, etc.), business secrets, and the application's internal environment.
