What it is

The Simple Random Posts Shortcode plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'container_right_width' attribute of the 'simple_random_posts' shortcode in all versions up to, and including, 0.3 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.
