Webhook Payload
Webhook handlers that use req.body without validation.
One of 104 modules in the GateTest scan suite. Catches the issue before it reaches code review, and on paid tiers opens a pull request with the fix already written.

Why we catch it
OWASP-grade scanning that goes beyond CVE lookups into your actual code paths.
The Webhook Payload module sits in this category alongside 6 related modules. Together they form one of the layers of a GateTest scan — checks fire in parallel, findings cluster by root cause, and on paid tiers the AI auto-fix loop reads each finding, writes the fix, validates against the scanner, and opens a PR.
How GateTest covers webhook payload
- ✓Runs in every scan. Included on the Full ($99), Scan + Fix ($199), and Forensic Scan ($399) tiers. No additional configuration.
- ✓Free CLI.
npm i -g gatetest && gatetest --module webhookPayloadagainst any local repo. No paywall on the scanning itself. - ✓AI auto-fix PR. Scan + Fix tier opens a pull request with the fix, a regression test, and a pair-review by a second Claude. Forensic Scan tier adds per-finding diagnosis and cross-finding attack-chain correlation.
- ✓Honest confidence rating. Findings come with high / medium / low confidence so noisy patterns don't block the gate. The confidence-calibrator trainer reads customer suppressions and tightens rules over time.
