The GenerateBlocks plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.8.2 via Query Loop. This makes it possible for authenticated attackers, with contributor access and above, to see contents of posts and pages in draft or private status as well as those with scheduled publication dates.

The GenerateBlocks WordPress plugin before 1.4.0 does not validate the generateblocks/container block's tagName attribute, which could allow users with a role as low as contributor to perform Cross-Site Scripting attacks.
