Vulnerability Overview
The Event Espresso – Event Registration & Ticketing Sales plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in all versions up to, and including, 5.0.37.decaf. This makes it possible for unauthenticated attackers to perform an unauthorized action.
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, and no interaction from a victim user.
CWE-862: Missing Authorization
Reaching this weakness in Event Espresso <= 5.0.37.decaf takes no account at all. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Event Espresso the fix is 5.0.53.decaf: builds <= 5.0.37.decaf are affected, anything from 5.0.53.decaf onward is not.
Remediation
Update to version 5.0.53.decaf, or a newer patched version
How does WordSec protect against this?
This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Event Espresso 5.0.53.decaf closes this, and updating the plugin is the step that ends it.
