No. You have lost volume and tidiness, not quality. The only real risk is what gets in through a fouled airlock, which is why the sanitising matters more than the mess.

Bad for your kitchen, fine for the mead, and switch to the tube now rather than hoping. An airlock that has had foam through it is contaminated and it will keep clogging as long as the krausen is rising.
Sanitised tube from the top of the fermenter into a jar of sanitiser or water, and the foam has somewhere to go. Clean up around the outside, put a tray underneath, and let it get on with it. The active phase usually settles within the first several days.
