Name of the Vulnerable Software and Affected Versions Show YouTube video plugin for WordPress versions prior to 1.2

Description The Show YouTube video plugin for WordPress is susceptible to Stored Cross-Site Scripting through the plugin’s 'syv' shortcode. This is due to inadequate input sanitization and output escaping of user-supplied attributes. Authenticated attackers with contributor-level access or higher can inject arbitrary web scripts into pages. These scripts will execute when a user accesses the affected page.
