Description
The Weaver Xtreme Theme Support plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's '[youtube]' and '[vimeo]' shortcodes in versions up to, and including, 6.2.5 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page
