From Breach to Hardened: A Laravel Rescue Engagement

The challenge

The client came to us after noticing signs of compromise on a Laravel application inherited from a previous developer — unexplained admin activity in the logs, and a support ticket from a customer who could see another customer's order history. Nobody on the client's current team had audited the codebase since it shipped. The immediate need was containment; the real need was finding every way in, not just the one already found, and closing all of them.

This is a representative engagement — it composites patterns we see across multiple Laravel rescue projects, not one named client. The vulnerability classes and remediation steps below are real; the specific business is not.

What the audit found

Two vulnerability classes accounted for the incident and the ongoing exposure:

An authentication-bypass class — a password-reset flow that didn’t invalidate the reset token after first use, letting a captured token be replayed to take over an account days after the original request was sent
An IDOR class — an order-history endpoint that trusted the ID in the URL instead of checking it against the logged-in customer, so incrementing a number in the address bar returned someone else’s order

Supporting findings rounded out the report: outdated dependencies carrying disclosed CVEs, APP_DEBUG left on in production, and an admin account still running its default credentials from initial setup.

Contain, then diagnose

The first 24 hours focused on containment, not root-cause analysis: compromised credentials revoked, the flagged admin account disabled, and the reset-token flow taken offline while the full audit ran in parallel. Only once the bleeding stopped did the complete codebase and dependency review begin.

The 10-day remediation

Every finding shipped with a fixed-price fix, not an open-ended hourly estimate. The reset-token flow was rebuilt to invalidate on first use and expire on a short window; every record-scoped endpoint got an ownership check added, then got re-tested by trying to break it the same way the original bug was exploited; dependencies were updated past every CVE-flagged version; debug mode went off, and secrets were rotated out of the repository and into environment-managed storage.

Hardened and monitored

The engagement closed with the client moved onto an ongoing care plan — uptime and security monitoring, a same-day response line, and a quarterly re-audit scheduled so the next attempt gets caught before it does damage, not discovered from a customer support ticket.
