Cost Calculator Builder

Plaintext payment gateway secret key exposure in the Cost Calculator Builder WordPress plugin (all versions ≤ 4.0.11) allows any unauthenticated remote visitor to harvest Stripe, Razorpay, and PayPal merchant credentials directly from page HTML source. The plugin embeds live API secret keys in the frontend template body when the 'use in all calculators' global payment gateway option is active, making those keys readable without any authentication or special tooling.
