At a glance

CVE-2024-1295 is a medium-severity Missing Authorization vulnerability in the The Events Calendar WordPress plugin, affecting versions <= 6.4.0. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 6.4.0.1; sites on affected versions should update now. Disclosed May 2024, reported by Scott Kingsley Clark.

Vulnerability Overview

Multiple plugins and/or themes for WordPress are vulnerable to unauthorized access of data due to a insufficient capability checks and restrictions on a function in various versions. This makes it possible for authenticated attackers, with Contributor-level access and above, to access arbitrary events that they should not have access to.

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-862: Missing Authorization

Reaching this weakness in The Events Calendar <= 6.4.0 takes an account at Contributor level or above. 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 The Events Calendar the fix is 6.4.0.1: builds <= 6.4.0 are affected, anything from 6.4.0.1 onward is not.

Remediation

Update to version 6.4.0.1, 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: The Events Calendar 6.4.0.1 closes this, and updating the plugin is the step that ends it.
