CVE-2026-39710

Vulnerability

Overview

The RT-Theme 18 | Extensions plugin for WordPress (versions up to and including 2.5) contains a Cross-Site Request Forgery (CSRF) vulnerability. This flaw arises because the plugin does not properly validate or enforce anti-CSRF tokens on sensitive actions, allowing an attacker to craft malicious requests that can be executed by an authenticated administrator without their knowledge [1].

Exploitation

Requirements

Exploitation requires user interaction: a privileged user (such as an administrator) must be tricked into clicking a malicious link, visiting a crafted page, or submitting a specially designed form while logged into the WordPress admin panel. No direct authentication is needed for the attacker, but the victim must have an active session with sufficient privileges to perform the targeted actions [1].

Impact

If successfully exploited, an attacker can force the victim to perform unintended actions under their current authentication, such as modifying plugin settings, creating new admin users, or changing site configurations. This can lead to partial compromise of the WordPress site, depending on the capabilities of the targeted actions [1].

Mitigation

The vendor has not released a patched version as of the publication date. Users are strongly advised to update the plugin immediately if a fix becomes available. If updating is not possible, contacting the hosting provider or a web developer for assistance is recommended. This vulnerability is noted as being used in mass-exploit campaigns, so prompt action is critical [1].
