Yes, Supabase apps can be hacked if not properly secured. The most common vulnerabilities include exposed API keys, missing database security, and weak authentication.
Supabase apps are built on modern technologies that are secure by design, but security requires proper configuration. Common attack vectors include:
2. **API Key Theft**: Secrets hardcoded in frontend code can be extracted and abused.
3. **Authentication Bypass**: Weak password policies and missing rate limiting enable account takeover.
4. **XSS Attacks**: If user input isn't properly sanitized, attackers can inject malicious scripts.
The good news is that all these issues are preventable with proper security practices. VAS scans for these vulnerabilities automatically.
