Technical details

The vulnerability is a stored XSS flaw in the 'date' shortcode attribute handler due to insufficient input sanitization and output escaping. The vulnerable code processes the format-date shortcode without properly sanitizing or escaping user-supplied input. An authenticated attacker with contributor-level access or above can inject arbitrary JavaScript code via the shortcode attribute, which persists in the page content and executes in the browsers of all users who view that page. Exploitation requires an administrator to enable the wppb_toolbox_shortcodes_settings[format-date] option. The vulnerability affects all versions up to and including 4.0.0, and patches should be available in later releases.
