Proof-driven API Security Testing for organizations in E-Commerce. We deliver validated exploit evidence, not automated scanner noise.
Free Scoping CallE-Commerce Vulnerability Intelligence
E-commerce platforms process millions of payment transactions daily. A single checkout flow vulnerability can expose card data at scale, trigger PCI non-compliance fines, and permanently damage consumer trust.
Server-Side Request Forgery in Product Import Pipelines
SSRF vulnerabilities in product data import and image processing pipelines enabling attackers to access internal cloud metadata services and pivot to backend infrastructure.
Price Manipulation and Cart Tampering
Client-side price validation allowing attackers to modify product prices, manipulate discount codes, and bypass payment amount verification in the checkout flow.
Stored XSS in User-Generated Content
Product reviews, seller profiles, and marketplace listings vulnerable to stored cross-site scripting that enables customer session hijacking and credential theft.
Magecart-Style Payment Skimming
Third-party JavaScript injection and supply-chain attacks on checkout pages that intercept and exfiltrate payment card data in real-time.
