GenerateBlocks <= 1.9.1 - Authenticated (Contributor+) Sensitive Information Exposure via 'get_image_description'

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.
