FormCraft permits unauthenticated server-side request forgery
FormCraft through 3.9.15 lets an unauthenticated attacker supply a destination that reaches an undisclosed server-side fetch operation. This can make the WordPress server send requests to attacker-selected or internal resources. The Patchstack CNA record does not disclose the route, action, URL parameter, fetch function, allowed schemes or response visibility.
