SECURITY TESTING FOR MARKETPLACE PLATFORMS

Indie hackers build marketplaces for everything – freelancer platforms, rental sites, niche job boards. Vibe-coded marketplace apps often lack the escrow logic, review verification, and fraud prevention that two-sided platforms need. One commission bypass can wipe out your revenue.

Scan your marketplace platforms for vulnerabilities

Why security matters for marketplace platforms

Marketplace Platforms handle sensitive data and business-critical operations. A single vulnerability can lead to data breaches, financial loss, and damaged reputation. VibeEval automatically tests for the most common security issues specific to marketplace platforms.

Top vulnerabilities in marketplace platforms

Escrow Bypass

Payment escrow logic that can be circumvented, allowing sellers to receive funds before fulfilling orders or buyers to reclaim payments after receiving goods.

Seller Verification Bypass

Incomplete identity verification flows that allow fraudulent sellers to list items without proper validation of their credentials or business information.

Review Manipulation

Rating and review systems that can be gamed through fake accounts, self-reviews, or API manipulation to inflate or deflate seller reputation scores.

Commission Evasion

Transaction flows that allow buyers and sellers to complete deals off-platform or manipulate transaction amounts to reduce marketplace commission fees.

Listing Data Injection

Product or service listings that accept unvalidated HTML, scripts, or redirect URLs that can be used to phish buyers or inject malicious content.

Dispute Resolution Abuse

Dispute and refund processes that can be exploited to receive both the product and a full refund by manipulating dispute evidence or timing.

Frequently asked questions

How does VibeEval test marketplace payment flows?

VibeEval simulates the full buyer-seller transaction lifecycle, testing escrow logic, commission calculations, and refund processes for bypass vulnerabilities.

Can VibeEval detect fake review vulnerabilities?

Yes. VibeEval tests whether reviews can be submitted without verified purchases, whether rating APIs lack rate limiting, and whether review authenticity checks can be bypassed.

Does VibeEval test seller onboarding security?

VibeEval checks seller registration and verification flows for bypass vulnerabilities, including identity verification steps and document upload validation.

What makes marketplace security different from other apps?

Marketplaces have a unique two-sided trust problem. Both buyers and sellers can be attackers, and the platform must protect each party from the other while also protecting itself from fraud.

How do I prevent commission evasion on my marketplace?

Enforce all transactions through your platform, monitor for off-platform communication attempts, and validate transaction amounts server-side. VibeEval tests for common evasion techniques.
