Received Received - Intake

Stored XSS in LifePress WordPress Plugin

Publication date: 2026-05-12

Last updated on: 2026-05-12

Assigner: Wordfence

Description
The LifePress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'n' parameter of the lp_update_mds AJAX action in all versions up to, and including, 2.2.2. This is due to the `wp_ajax_nopriv_lp_update_mds` action being registered without nonce verification or capability checks, combined with insufficient input sanitization and output escaping when the series name is rendered in the admin settings page. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Executive Summary

The LifePress plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in the 'n' parameter of the lp_update_mds AJAX action in all versions up to and including 2.2.2.

This vulnerability exists because the AJAX action 'wp_ajax_nopriv_lp_update_mds' is registered without nonce verification or capability checks, and there is insufficient input sanitization and output escaping when the series name is displayed in the admin settings page.

As a result, unauthenticated attackers can inject arbitrary web scripts that execute whenever a user accesses the injected page.

Impact Analysis

This vulnerability allows unauthenticated attackers to inject malicious scripts into pages viewed by users, leading to potential compromise of user sessions, theft of sensitive information, or unauthorized actions performed on behalf of users.

Because the attack can be performed remotely without authentication, it increases the risk of widespread exploitation.

The CVSS score of 7.2 indicates a high severity impact with low attack complexity and no required privileges or user interaction.
