Gutenberg Essential Blocks vulnerabilities

The Gutenberg Essential Blocks WordPress plugin before version 6.4.0 does not verify that an attacker-supplied post type is publicly viewable before querying it in one of its public REST routes. This allows unauthenticated users to read published entries of custom post types that the site registered as non-public.

The Gutenberg Essential Blocks WordPress plugin before version 6.4.0 does not restrict access to one of its public REST routes and over-fetches a non-public WooCommerce per-product sales metric into the response. This allows unauthenticated users to read the lifetime number of units sold for any published product.

The Gutenberg Essential Blocks plugin for WordPress up to version 6.1.3 contains a Server-Side Request Forgery (SSRF) vulnerability in the `save_ai_generated_image()` function. Authenticated attackers with Author-level access or higher can make requests to arbitrary external and internal locations, potentially reading or modifying data from internal services.
