An attacker who can control a button URL can supply an otherwise allowed HTTPS URL containing whitespace and additional attributes, including an event handler, and execute JavaScript in a user's browser when the affected button is interacted with. Successful exploitation can compromise the confidentiality and integrity of data accessible to the affected application.
