Common TypeScript Vulnerabilities

Critical security issues we identify in TypeScript Web3 applications

Frontend Security Issues

Cross-Site Scripting (XSS)

Unvalidated user input rendering in React components, potentially modifying transaction data.

Client-Side Bypasses

Access control checks that can be bypassed through browser developer tools.

Hardcoded Secrets

API keys, private keys, or sensitive endpoints exposed in frontend bundles.

Backend & API Issues

Injection Attacks

SQL injection, NoSQL injection, and command injection through unvalidated inputs.

Authentication Flaws

Weak JWT implementations, session management issues, and privilege escalation.

CORS Misconfigurations

Overly permissive CORS policies allowing unauthorized cross-origin requests.

How our TypeScript audits prevent real security incidents

Critical XSS Prevention

Initia Protocol Frontend Audit

In our recent collaboration with Pashov Audit Group for Initia Protocol, we identified a high-severity XSS vulnerability in the TypeScript frontend. Unvalidated user input was being rendered directly in React components, which could have allowed attackers to:

  • • Execute malicious scripts in users' browsers
  • • Modify transaction data before signing
  • • Steal sensitive user information and wallet data
  • • Redirect users to phishing sites

By identifying and fixing this vulnerability before launch, we helped secure user flows and protect sensitive data for thousands of potential users.
