Descriptions

The Cloudflare Image Resizing plugin for WordPress is vulnerable to Remote Code Execution due to missing authentication and insufficient sanitization within its hook_rest_pre_dispatch() method in all versions up to, and including, 1.5.6. This makes it possible for unauthenticated attackers to inject arbitrary PHP into the codebase, achieving remote code execution.

Cloudflare Image Resizing versions 1.5.6 and below suffer from an unauthenticated remote code execution vulnerability via the rest_pre_dispatch hook.
