Premmerce Wishlist for WooCommerce <= 1.1.10 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Wishlist Deletion

The Premmerce Wishlist for WooCommerce plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.1.10. This is due to a missing capability check on the deleteWishlist() function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary wishlists.
