Stored XSS in WordPress Survey Plugin Affects Multi-Site Admins

Publication date: 2026-03-21

Last updated on: 2026-03-21

Assigner: Wordfence

Description
The Survey plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 1.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Executive Summary

The Survey plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in all versions up to and including 1.1. This vulnerability arises because the plugin does not properly sanitize input or escape output in the admin settings. As a result, authenticated users with administrator-level permissions or higher can inject malicious web scripts into pages. These scripts execute whenever any user accesses the affected pages.

This vulnerability specifically affects multi-site WordPress installations and installations where the unfiltered_html capability has been disabled.

Impact Analysis

This vulnerability can allow attackers with administrator-level access to inject malicious scripts into the website. These scripts can execute in the browsers of users who visit the injected pages, potentially leading to theft of sensitive information, session hijacking, or other malicious actions.

Because the vulnerability requires high privileges (administrator-level) and affects multi-site or restricted HTML installations, the risk is somewhat limited but still significant in those environments.
