Vulnerability Overview

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 Email Tracker <= 5.2.6 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 Email Tracker the fix is 5.2.7: builds <= 5.2.6 are affected, anything from 5.2.7 onward is not.
Remediation
Update to version 5.2.7, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Email Tracker: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Email Tracker 5.2.7 closes this, and updating the plugin is the step that ends it.
