Stored XSS in Ecover Builder For Dummies WordPress Plugin

Publication date: 2026-03-21

Last updated on: 2026-03-21

Assigner: Wordfence

Description
The Ecover Builder For Dummies plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'id' parameter of the 'ecover' shortcode in all versions up to and including 1.0. This is due to insufficient input sanitization and output escaping on the user-supplied 'id' shortcode attribute. 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 Ecover Builder For Dummies plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in the 'id' parameter of the 'ecover' shortcode. This vulnerability exists in all versions up to and including 1.0. It occurs because the plugin does not properly sanitize or escape user input supplied to the 'id' attribute of the shortcode.

As a result, authenticated users with Contributor-level access or higher can inject malicious scripts into pages. These scripts will execute whenever any user accesses the affected page.

Impact Analysis

This vulnerability can allow attackers with Contributor-level access or above to inject arbitrary web scripts into pages. These scripts can execute in the context of users visiting those pages, potentially leading to theft of user credentials, session hijacking, defacement, or other malicious actions.

Since the attack requires authenticated access, it may be limited to insiders or users with some level of trust, but the impact can still be significant as it affects all users who view the injected content.
