At a glance
This record tracks a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Child Theme Generator WordPress plugin, affecting versions <= 2.2.7. It carries a CVSS score of 5.4 (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 November 2021.
Vulnerability Overview
The Child Theme Generator plugin for WordPress is vulnerability to Cross-Site Request Forgery in versions up to, and including, 2.2.7 due to insufficient nonce validation on the section_remove function. This makes it possible for attackers to delete arbitrary folders on the affected site, if they can successfully trick a site's 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)
Reaching this weakness in Child Theme Generator <= 2.2.7 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 Child Theme Generator yet, so installs running <= 2.2.7 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 Child Theme Generator: 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.
