The Offload, AI & Optimize with Cloudflare Images plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.10.2 via the 'account-id' parameter parameter. This is due to insufficient privilege enforcement on the cf images do setup AJAX handler, which requires only the upload files capability (Author+) rather than manage options before writing to wp-config.php, combined with the absence of single-quote escaping — sanitize text field() does not strip single quotes, and filter input(INPUT POST) bypasses wp magic quotes() slashing — allowing a single quote in the account-id or api-key parameter to break out of the single-quoted PHP string literal in the write config() define() statement. This makes it possible for authenticated attackers, with author-level access and above, to execute code on the server. This is possible because the 'cf-images-nonce' nonce required by the AJAX handler is exposed to all Author-level and above users on wp-admin/upload.php via the CFImages JavaScript object, meaning any upload-capable user can satisfy the nonce check and reach the vulnerable wp-config.php write path.

**Name of the Vulnerable Software and Affected Versions** WP User Manager – User Profile Builder & Membership versions prior to 2.9.18 **Description** The plugin is susceptible to Local File Inclusion, a condition where an application includes files on a local server unexpectedly. This occurs through the `profile template scope` function, allowing unauthenticated attackers to include and execute arbitrary .php files. This can lead to the execution of PHP code, bypassing of access controls, or the acquisition of sensitive data, particularly when .php files can be uploaded to the server. **Recommendations** Update the plugin to version 2.9.18 or later. As a temporary workaround, restrict access to the `profile template scope` function to minimize the risk of exploitation.
