Vulnerability Overview
The Event Tickets and Registration plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to 5.29.0.1 due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with contributor-level access and above, 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 interaction from a victim user.
CWE-639: Authorization Bypass Through User-Controlled Key
Reaching this weakness in Event Tickets and Registration < 5.29.0.1 takes an account at Contributor level or above. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.
Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For Event Tickets and Registration the fix is 5.29.0.1: builds < 5.29.0.1 are affected, anything from 5.29.0.1 onward is not.
Remediation
Update to version 5.29.0.1, or a newer patched version
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Event Tickets and Registration 5.29.0.1 closes this, and updating the plugin is the step that ends it.
