CVE-2026-121857 is a medium-severity Incorrect Authorization vulnerability in the Event Tickets with Ticket Scanner WordPress plugin, affecting versions <= 3.1.13.

Vulnerability Overview

The Event Tickets with Ticket Scanner plugin for WordPress is vulnerable to unauthorized access in all versions up to, and including, 3.1.13. This is due to a missing capability check on a function. This makes it possible for authenticated 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 interaction from a victim user.

CWE-863: Incorrect Authorization

Reaching this weakness in Event Tickets with Ticket Scanner <= 3.1.13 takes a caller who can reach the endpoint. Incorrect authorization means a permission check exists but evaluates the wrong thing, so it passes for callers it was meant to stop.

The action runs for users the code intended to exclude, with the same effect as having no check at all. For Event Tickets with Ticket Scanner the fix is 3.1.14: builds <= 3.1.13 are affected, anything from 3.1.14 onward is not.

Remediation

Update to version 3.1.14, 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 with Ticket Scanner 3.1.14 closes this, and updating the plugin is the step that ends it.
