WordPress AGE-GATE Plugin Remote Code Execution Vulnerability

The AGE-GATE plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.0 via the 'width (and height)' parameter.

The flaw is due to missing authentication, capability checks, and nonce verification on the standalone admin.php endpoint, combined with unsanitized injection of POST parameters directly into generated PHP source written to an included file.

• Affects all versions up to and including 1.0.
• Requires no authentication; unauthenticated attackers can execute code on the server.
• admin.php does not load WordPress and carries no ABSPATH guard, making it a fully unauthenticated entry point.

This makes it possible for unauthenticated attackers to execute code on the server.
