Description
mall4j through 4.0 contains an improper authorization vulnerability that allows authenticated storefront customers to delete other shoppers' cart items through an operator precedence error in the cleanExpiryProdList SQL statement. Attackers can send one DELETE request to /p/shopCart/cleanExpiryProdList to remove every user's cart entries for off-shelf products, which do not return when products are restocked.
