WordPress, Cross-Site Request Forgery (CSRF), CVE-2025-0393 (Critical)

The Royal Elementor Addons and Templates plugin for WordPress, up to version 1.7.1006, is vulnerable to Cross-Site Request Forgery (CSRF) due to missing or incorrect nonce validation in the `wpr_filter_grid_posts()` function. Nonces (number used once) are security tokens used to protect against CSRF attacks by ensuring that requests originate from the intended user. In this case, the absence of proper nonce validation allows unauthenticated attackers to forge requests. By tricking an administrator into clicking a malicious link or visiting a compromised page, the attacker can inject malicious web scripts or perform unauthorized actions on the target site. This vulnerability is particularly dangerous because it requires minimal user interaction and can lead to full site compromise if exploited successfully.
