Description
The Video Onclick plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `youtube` shortcode in all versions up to, and including, 0.4.7 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
Problem types
CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
