PCI Payment Page Script Audit: requirement 6.4.3 and 11.6.1 on your checkout markup

PCI DSS 4.0.1 requirements 6.4.3 and 11.6.1 have been mandatory since 2025-03-31, and the PCI SSC revised FAQ 1331 on 2026-08-04 so a QSA agreement alone no longer marks them not applicable. This reads a checkout page and names every script that has no authorization method, no integrity method and no inventory row.

Install

npx @readystack/pci-payment-page-script-audit file

Node 18+. The same 26 rules as the VS Code extension, from a terminal or CI.

Free

• Audit the checkout page you have open against all 26 PCI script-security rules - every script, every line, the requirement each one fails and the fix, no key asked.
• --rules lists every rule

With a licence ($29 once)

• Export the dated 6.4.3 script inventory as the evidence file you hand the assessor, across every payment page in the repository, with CI output that fails a build when an unauthorized script appears.

@readystack/pci-payment-page-script-audit --dir ./templates --report html --out report.html

A PCI consultant bills about $76/hour in the US in 2026 (Salary.com, August 2026) and a QSA-assisted SAQ runs $5,000-$20,000; building the script inventory by hand is the part you are paying for.
