Executive Summary

The Cost Calculator Builder plugin for WordPress has a vulnerability in all versions up to and including 4.0.11 that allows sensitive information exposure. Specifically, when the 'use in all calculators' option is enabled for one or more payment gateways, unauthenticated attackers can extract plaintext secret keys for Stripe, Razorpay, and PayPal from the page source of any page containing a calculator.

This means attackers can access critical payment gateway credentials embedded in the page, which should normally be protected.

Impact Analysis

This vulnerability can have a significant impact because it enables attackers to gain full control over the merchant's payment gateway accounts by extracting secret keys.

  • Attackers can potentially perform unauthorized transactions or manipulate payment processing.
  • It can lead to financial loss, fraud, and damage to the merchant's reputation.
  • Since the exposure is unauthenticated and remote, it increases the risk of widespread exploitation.
