Description
The Bulma Shortcodes plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'type' shortcode attribute in the bulma-notification shortcode in all versions up to, and including, 1.0. This is due to insufficient input sanitization and output escaping. 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.
