Proprietary code exposure to third-party servers.
Check Settings → Privacy for Zero Data Retention status.
Enable Zero Data Retention for sensitive projects.
AI-Generated Vulnerabilities
highCascade suggests code with security flaws.
Injection, auth bypass, and other vulnerabilities in generated code.
Review all AI suggestions. Run security scans.
Never auto-accept security-critical code. Scan before deployment.
Medium Severity Issues
Workspace Trust Disabled
mediumMalicious .windsurf files can execute on project open.
Code execution when opening untrusted repositories.
Check Workspace Trust setting in preferences.
Enable Workspace Trust. Review project files before opening.
How to Prevent These Issues
- Run automated security scans before every deployment
- Configure database access controls (RLS/Security Rules) first
- Store all secrets in environment variables, never in code
- Enable email verification and strong password policies
- Add security headers to your hosting configuration
- Review AI-generated code for security before accepting

Get Starter ScanFrequently Asked Questions
What are the most common Windsurf security issues?
The most common issues are: exposed API keys/secrets, missing database access controls (RLS or Security Rules), weak authentication configuration, and missing security headers. These account for over 80% of vulnerabilities in Windsurf applications.
How do I find security issues in my Windsurf app?
Run a VAS security scan for automated detection of common vulnerabilities. Manually check: database access controls, search code for hardcoded secrets, verify authentication settings, and test security headers. VAS catches all of these automatically.
Are Windsurf security issues fixable?
Yes, nearly all Windsurf security issues are configuration problems with straightforward fixes. Missing RLS, exposed secrets, weak auth—all have clear remediation steps. Most fixes take under an hour to implement.
How quickly can Windsurf security issues be exploited?
Exposed databases and API keys can be discovered within minutes using automated scanners. Attackers actively scan for common patterns. This is why security configuration must happen before deployment, not after.
Does Windsurf have built-in security?
Windsurf provides security features, but they require configuration. Security isn't automatic—you must enable database access controls, manage secrets properly, configure auth settings, and add security headers. The tools exist; you must use them.
What are the 94 Chromium CVEs in Windsurf?
Security audits in 2024-2025 found 94 Chromium-based vulnerabilities including memory corruption, sandbox escapes, and RCE vectors. Codeium patches these regularly—keep Windsurf updated to the latest version.
