The Show Posts list – Easy designs, filters and more plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'post type' shortcode attribute in the 'swiftpost-list' shortcode in all versions up to, and including, 1.1.0 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.
