What to do when your Magento store fails a PCI scan
A plain-English response plan for Magento stores that fail PCI because of missing patches, exposed files or public configuration issues.
Do not rush straight into production changes
A failed PCI scan feels urgent, but a rushed fix can create a bigger outage. First, capture the scan output, identify whether the issue is Magento core, an extension, hosting config or a public file exposure, and make sure you have rollback.
The usual Magento PCI findings
Most Magento PCI failures are not exotic. They tend to be missing security patches, exposed composer files, visible admin paths, weak headers, old TLS settings or stale PHP versions.
- Missing Magento security patch.
- Public composer.json or composer.lock.
- Magento version disclosure.
- Missing HSTS, X-Content-Type-Options or CSP.
- Default admin path still reachable.
What evidence your assessor needs
After remediation, keep the before/after scan, the deployment notes, the patch list, the test record and the date of production change. A short written report is often enough for the PCI follow-up.
