Simple Shopping Cart 5.1.3 - 5.3.2 - Contributor+ Price Manipulation via Price Verification Bypass

The Simple Shopping Cart WordPress plugin before 5.3.3 does not verify submitted product prices against a value only the site owner can set, allowing users with the Contributor role and above to register attacker-chosen prices for existing products, which any visitor can then use to add those products to the cart at that price.
