The GenerateBlocks plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.9.1 via the 'get_image_description' function. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract sensitive data including the content of private, draft, and scheduled posts and pages.
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
