Received Received - Intake
Stored XSS in Page Builder: Pagelayer Button Widget

Publication date: 2026-04-08

Last updated on: 2026-04-08

Assigner: Wordfence

Description
The Page Builder: Pagelayer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Button widget's Custom Attributes field in all versions up to, and including, 2.0.8. This is due to an incomplete event handler blocklist in the 'pagelayer_xss_content' XSS filtering function, which blocks common, but not all, event handlers. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Executive Summary

The Page Builder: Pagelayer plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in its Button widget's Custom Attributes field. This vulnerability exists in all versions up to and including 2.0.8. It is caused by an incomplete event handler blocklist in the 'pagelayer_xss_content' XSS filtering function, which blocks some common event handlers but not all. As a result, authenticated users with Contributor-level access or higher can inject malicious scripts into pages. These scripts execute whenever any user accesses the infected page.

Impact Analysis

This vulnerability allows attackers with Contributor-level access or above to inject arbitrary web scripts into pages. These scripts can execute in the context of any user who views the infected page, potentially leading to unauthorized actions such as stealing session cookies, defacing content, or performing actions on behalf of the user without their consent.
