The plugin called Postcasa Shortcode for WordPress has a security issue. It is possible for attackers who have contributor-level access or higher to insert harmful scripts into pages. This can happen in versions 1.0 and below, because the plugin does not properly filter and protect user input. These scripts can then be executed when a user visits the affected page.
