Exposure of Sensitive Information to an Unauthorized Actor
The GiveWP plugin for WordPress is vulnerable to Sensitive Information Disclosure in versions up to, and including, 2.20.2 via the /donor-wall REST-API endpoint which provides unauthenticated users with donor information even when the donor wall is not enabled. This functionality has been completely removed in version 2.20.2.
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.
