At a glance
CVE-2022-0681 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Simple Membership WordPress plugin, affecting versions < 4.1.0. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high integrity impact). Exploitation requires no authentication. The issue is fixed in version 4.1.0; sites on affected versions should update now. Disclosed February 2022, reported by Muhamad Hidayat.
Vulnerability Overview
The Simple Membership WordPress plugin before 4.1.0 does not have Cross-Site Request Forgery (CSRF) protections in place when deleting Transactions, which could allow attackers to make a logged in admin delete arbitrary transactions via a CSRF attack
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. A successful exploit has high impact on integrity.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Simple Membership < 4.1.0 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. For Simple Membership the fix is 4.1.0: builds < 4.1.0 are affected, anything from 4.1.0 onward is not.
Remediation
Update to version 4.1.0, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Simple Membership: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Simple Membership 4.1.0 closes this, and updating the plugin is the step that ends it.
