GHSA-52W9-QFC2-5XQ5

Vulnerability from github – Published: 2025-08-19 09:30 – Updated: 2025-08-19 09:30

Details

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.

Severity ?

9.8 (Critical)


                  
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
