Executive Summary

The Video Onclick plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in its `youtube` shortcode in all versions up to and including 0.4.7.

This vulnerability exists because the plugin does not properly sanitize or escape user-supplied attributes, allowing attackers with contributor-level access or higher to inject malicious scripts.

These injected scripts execute whenever any user accesses the affected page, potentially compromising user security.

Impact Analysis

This vulnerability can allow an authenticated attacker with contributor-level access to inject arbitrary web scripts into pages.

When other users visit these pages, the malicious scripts execute in their browsers, which can lead to theft of sensitive information, session hijacking, or other malicious actions.

Because the attack requires contributor-level access, it may be limited to insiders or users with some level of trust, but the impact on users who view the injected content can be significant.
