Executive Summary

The CI HUB Connector plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in the 'id' attribute of the cihub_metadata shortcode. This vulnerability exists in all versions up to and including 1.2.106 due to insufficient input sanitization and output escaping.

Authenticated attackers with Contributor-level access or higher can exploit this flaw to inject arbitrary web scripts into pages. These scripts will execute whenever any user accesses the injected page.

Impact Analysis

This vulnerability allows attackers with Contributor-level access or above to inject malicious scripts into WordPress pages. When other users visit these pages, the injected scripts execute, potentially leading to unauthorized actions such as stealing user credentials, session hijacking, or performing actions on behalf of the user.

Because the vulnerability is a Stored Cross-Site Scripting issue, it can persist on the site and affect multiple users, increasing the risk and impact.
