Description
The Essential Blocks for Gutenberg plugin for WordPress is vulnerable to unauthorized access to AJAX actions due to a missing capability check on several functions in versions up to, and including, 4.2.0. This makes it possible for authenticated attackers, with subscriber-level access and above, to invoke those functions. A nonce check was performed in all of them. However, the nonce was leaked on the profile page. CVE-2023-51360 appears to be a duplicate of this issue.
