At a glance

CVE-2025-8091 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the EventON WordPress plugin, affecting versions <= 2.4.7. 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 2.4.8; sites on affected versions should update now. Disclosed August 2025, reported by Moose Love.

Vulnerability Overview

The EventON Lite plugin for WordPress is vulnerable to Information Exposure in all versions less than, or equal to, 2.4.6 via the add_single_eventon and add_eventon shortcodes due to insufficient restrictions on which posts can be included. This makes it possible for unauthenticated attackers to extract data from password protected, private, or draft posts 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-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in EventON <= 2.4.7 takes an account at Contributor level or above. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For EventON the fix is 2.4.8: builds <= 2.4.7 are affected, anything from 2.4.8 onward is not.

Remediation

Update to version 2.4.8, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: EventON 2.4.8 closes this, and updating the plugin is the step that ends it.
