CVE-2025-5733 is a medium-severity Insertion of Sensitive Information Into Sent Data vulnerability in the Modern Events Calendar Lite WordPress plugin, affecting versions <= 7.21.9.

Vulnerability Overview

The Modern Events Calendar Lite plugin for WordPress is vulnerable to Full Path Disclosure in all versions up to, and including, 7.21.9. This is due improper or insufficient validation of the id property when exporting calendars. This makes it possible for unauthenticated attackers to retrieve the full path of the web application, which can be used to aid other attacks. The information displayed is not useful on its own, and requires another vulnerability to be present for damage to an affected website.

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-201: Insertion of Sensitive Information Into Sent Data

The code transmits data to another actor, but a portion of the data includes sensitive information that should not be accessible to that actor.

Remediation

Update to version 7.22, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Modern Events Calendar Lite 7.22 closes this, and updating the plugin is the step that ends it.
