Executive Summary

The Advanced iFrame plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in the 'additional' parameter in all versions up to and including 2026.1. This vulnerability arises because the plugin does not properly sanitize input or escape output. As a result, authenticated users with contributor-level access or higher can inject malicious web scripts into pages. These scripts execute whenever any user accesses the injected page.

Impact Analysis

This vulnerability can allow attackers with contributor-level access or above to inject arbitrary scripts into web pages. These scripts can execute in the context of other users visiting the affected pages, potentially leading to theft of user credentials, session hijacking, defacement, or other malicious actions. Because the attack requires authenticated access, it poses a risk primarily within environments where multiple users have editing permissions.
