CVE-2025-5933
At a glance
CVE-2025-5933 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the RD Contacto WordPress plugin, affecting versions <= 1.4. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed July 2025, reported by Nabil Irawan.
Vulnerability Overview
The RD Contacto plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.4. This is due to missing or incorrect nonce validation on the rdWappUpdateData() function. This makes it possible for unauthenticated attackers to update plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.
CWE-352: Cross-Site Request Forgery (CSRF)
RD Contacto <= 1.4 carries this weakness at rdWappUpdateData(), and reaching it takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. No fixed build of this plugin is recorded for RD Contacto yet, so installs running <= 1.4 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
The attempt arrives as an ordinary request to RD Contacto: WordSec's web application firewall inspects request payloads before WordPress loads them. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
