PrestaShop Security Audit & Hardening Report

A PrestaShop security audit from people who harden real PrestaShop stores

PrestaShop is a constant target. Magecart card skimmers, SQL injection, Smarty template RCE, compromised admin accounts and abandoned modules all turn up on live stores every week. This Security Audit reviews your live PrestaShop store end to end and hands you a prioritised hardening plan: every risk, its severity, and the precise fix, with anything critical flagged for immediate action.

It is built specifically for PrestaShop. We know the platform's attack surface because we run a PrestaShop store, build the security tooling merchants use in production, and have cleaned real infections and patched live vulnerabilities. You get a diagnosis grounded in real operations, not a scanner printout and not scare tactics.

Who it is for

Any merchant who handles customer or payment data and wants to know their real exposure: before a busy season, before a PCI or insurer question, after inheriting a store, or when you simply have not had an expert look. It also suits agencies wanting an independent PrestaShop second opinion on a client store, and merchants who have had one incident and want to be sure the door is actually shut.

How we run the review

We work from your real store rather than a template. The review combines automated scanning with manual inspection of the places scanners cannot reason about: we compare your core and module files against known-good PrestaShop releases to surface injected or modified code, walk the template and JavaScript layer for skimmer patterns and obfuscated payloads, query the database for suspicious admin sessions, rogue employees and tampered configuration, and read your configuration for the misconfigurations that quietly widen the attack surface. Every finding is reproduced and evidenced before it goes in the report, so you are not chasing a false alarm.

How findings are ranked

Each finding is scored on three axes: severity (what an attacker could actually do, from card-data theft and remote code execution down to information disclosure), likelihood (how exposed the path is in your real configuration), and remediation effort (a five-minute setting change versus a core upgrade). That gives you a defensible priority order instead of a flat list, so the same-day items rise to the top and the low-value busywork is honestly marked as such. The full scoring model and a sample finding matrix are in the Methodology & Sample Report tab.

Example findings you might see

The report names concrete things, not categories: a payment-page template loading an unfamiliar external script (a classic Magecart tell); a back office reachable on the default /admin-style path with no IP restriction and no 2FA; three employee accounts that have not logged in for a year and one with full SuperAdmin rights nobody recognises; a module two major versions behind a published security fix; _PS_MODE_DEV_ left enabled in production leaking stack traces; or a database export sitting in a web-reachable folder. Each is mapped to the exact fix and ordered by what it would cost an attacker versus what it costs you to close.

What you get

• A severity-scored risk report tailored to your store, version, host and module stack.
• Each finding mapped to a concrete remediation, ordered by severity, likelihood and effort.
• Critical issues called out for same-day action, with a clear hardening roadmap your team or developer can act on directly.
• A backup-and-recovery assessment: whether you could really restore clean after an incident.
• A short walkthrough call or email thread to talk your team through the priorities.

An audit, not incident response

This is an assessment and a plan. It is deliberately not active incident cleanup. If the audit uncovers an active compromise we will flag it immediately and outline the urgent containment steps, but the hands-on cleanup and any malware removal are scoped and quoted separately as priority work. Implementation of the recommended hardening is likewise a separate engagement; many fixes you can apply yourself with the report in hand. We also do not run intrusive penetration tests or load attacks against your live store, and we never alter your shop during the review.

Many of the controls we recommend are implemented with our open-code Security Revolution module (admin hardening, 2FA, login protection), but we will always tell you when no module is the answer and a setting, a host change or simply deleting a stale account is the right fix. For the infrastructure layer, pair this with a Hosting Audit. To see the full range, browse all Expert Services.

PrestaShop versions covered

We audit PrestaShop 1.6, 1.7, 8 and 9, including multistore, on any host and any theme. Findings account for your exact version, modules and configuration, so you are not paying for advice that does not apply to your store. We know the version-specific failure modes too: the 1.6 cookie and token weaknesses, the Smarty changes between 1.7 branches, and the new admin and configuration surface in 8 and 9.
