 "title": "Theme My Login <= 7.3.0 - Cross-Site Request Forgery to Multisite Site Creation via Signup Form",
 "description": "The Theme My Login plugin for WordPress is vulnerable to Cross-Site Request Forgery via the multisite signup form in all versions up to, and including, 7.3.0, due to missing nonce validation in the tml_ms_signup_handler() function. This makes it possible for unauthenticated attackers to create a new site owned by a logged-in user through the 'gimmeanotherblog' signup stage, using a forged request, if they can trick that user into performing an action such as clicking a link. This only affects multisite networks that allow site signups.",
