🚨 Severity: HIGH
💡 Vulnerability: The application was using the cryptographically insecure
Math.random()to generate potentially sensitive security tokens, including bargain coupon codes, store credit codes, and combo group IDs.🎯 Impact: Using a weak PRNG like
Math.random()allows an attacker to potentially predict generated codes. This could result in unauthorized discovery of valid discount codes or store credits, leading to financial loss for the platform.🔧 Fix:
generateSecureCode()utility inlib/utils.tsthat relies on the cryptographically securecrypto.getRandomValues().app/api/bargain/route.ts,lib/actions/admin.ts, andlib/cart-context.tsxto use the new utility instead of inlineMath.random()loops.✅ Verification: Verified by checking out the code modifications manually and running the codebase test suite (
bun test), ensuring zero failures and that code-generation paths use secure randomness.PR created automatically by Jules for task 7096090082755706096 started by @f4teless
