4 Security Issues Documented
Common vulnerabilities found in Turso applications
Critical Security Issues
Group access controls
criticalA common failure mode in Turso applications: group access controls. Left unchecked, this can lead to data exposure, unauthorized access, or service abuse.
Complete database exposure — attackers can read, modify, or delete all user data. For Turso apps that handle PII or payment data, this becomes a reportable breach (GDPR 72-hour notification).
Probe API/database endpoints without authentication. Any response containing user data confirms the gap.
Enable Row Level Security (Supabase) or Security Rules (Firebase) on every table. For custom backends, enforce authorization at the query layer — never client-side.
High Severity Issues
Auth token management
highA common failure mode in Turso applications: auth token management. Left unchecked, this can lead to data exposure, unauthorized access, or service abuse.
Account takeover of legitimate users. Attackers gain full access to victim accounts and any data/actions those accounts permit.
Attempt 20+ login requests with the same username in under 60 seconds. If all complete without rate limiting or lockout, the issue is present.
Enforce email verification, minimum password requirements, and rate limiting on auth endpoints. Test auth flows as unauthenticated and cross-user to verify access controls.
Medium Severity Issues
Edge replication security
mediumA common failure mode in Turso applications: edge replication security. Left unchecked, this can lead to data exposure, unauthorized access, or service abuse.
Account takeover of legitimate users. Attackers gain full access to victim accounts and any data/actions those accounts permit.
Attempt 20+ login requests with the same username in under 60 seconds. If all complete without rate limiting or lockout, the issue is present.
Scan your deployed application with a security tool that understands this stack. Address the specific findings — generic best practices don't catch platform-specific misconfigurations.
Embedded replica security
mediumA common failure mode in Turso applications: embedded replica security. Left unchecked, this can lead to data exposure, unauthorized access, or service abuse.
Account takeover of legitimate users. Attackers gain full access to victim accounts and any data/actions those accounts permit.
Attempt 20+ login requests with the same username in under 60 seconds. If all complete without rate limiting or lockout, the issue is present.
Scan your deployed application with a security tool that understands this stack. Address the specific findings — generic best practices don't catch platform-specific misconfigurations.
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 Turso 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 Turso applications.
How do I find security issues in my Turso 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 Turso security issues fixable?
Yes, nearly all Turso 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 Turso 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 Turso have built-in security?
Turso 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.
