A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.
Description
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.
