At a glance
CVE-2021-25113 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Dropdown Menu Widget WordPress plugin, affecting versions <= 1.9.7. It carries a CVSS score of 6.4 (reachable over the network; low attack complexity). No fixed release has been reported yet; treat installations running this software as exposed. Disclosed March 2022, reported by Krzysztof Zając.
Vulnerability Overview
The Dropdown Menu Widget WordPress plugin through 1.9.7 does not have authorisation and CSRF checks when saving its settings, allowing low privilege users such as subscriber to update them. Due to the lack of sanitisation and escaping, it could also lead to Stored Cross-Site Scripting issues
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 interaction from a victim user.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Dropdown Menu Widget <= 1.9.7 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 Dropdown Menu Widget yet, so installs running <= 1.9.7 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 Dropdown Menu Widget: 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.
