CVE-2025-12512
📋 TL;DR
The GenerateBlocks WordPress plugin up to version 2.1.2 has an information exposure vulnerability that allows authenticated users with Contributor-level permissions or higher to access sensitive metadata of other users. This occurs because the plugin's REST API endpoints lack proper authorization checks, enabling attackers to retrieve personally identifiable information (PII) like names, emails, phone numbers, and addresses. Any WordPress site using vulnerable versions of GenerateBlocks is affected.
