What is CVE-2026-104642?

The Simple Shopping Cart plugin for WordPress, prior to version 5.3.3, features a security flaw that allows users with the Contributor role or higher to submit arbitrary product prices. This vulnerability arises from the plugin's failure to validate submitted prices against a predetermined value, which is only accessible to the site owner. As a result, attackers can set malicious prices for products listed in the shopping cart, misleading prospective buyers and potentially leading to financial losses.

Affected Version(s)

Simple Shopping Cart 5.1.3 < 5.3.3

Exploit Proof of Concept (PoC)
