The Gutenberg Block Editor Toolkit – EditorsKit WordPress plugin before 1.31.6 does not sanitise and validate the Conditional Logic of the Custom Visibility settings, allowing users with a role as low contributor to execute Arbitrary PHP code

The EditorsKit plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation on the 'importstyles' function in versions up to, and including, 1.40.3. This makes it possible for authenticated attackers with administrator-level capabilities or above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

The Extendify plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'styles.blocks' Block Type Key in all versions up to, and including, 3.1.6 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is possible because registerIncoming() is hooked on restrequestbeforecallbacks and runs before WordPress evaluates the route's permissioncallback, meaning any unauthenticated POST, PUT, or PATCH request to a /wp/v2/global-styles route can trigger the vulnerable code path.
