PlanetScale Security Scanner
Using PlanetScale? Ensure your serverless MySQL database is properly secured.
Our automated security scanner analyzes your PlanetScale application for vulnerabilities, misconfigurations, and exposed secrets. Get a comprehensive security report in minutes, not days.
PlanetScale Security Considerations
PlanetScale makes development fast, but AI-generated code often skips security best practices:
- !Connection string exposure in frontend
- !Branch promotion security
- !Password security and rotation
- !Query patterns and injection prevention
Where Security Breaks in PlanetScale Apps
Built on a managed backend, PlanetScale applications share a recognizable fingerprint — which means attackers and automated scanners find them the same way every time. Based on real vulnerability patterns in PlanetScale deployments, the breakdown is 2 critical-impact issues, 2 high-impact, and 1 medium-or-lower.
No Row Level Security
MySQL/Vitess doesn't have RLS—must implement in application.
Fix: Build access control in application layer. Filter all queries by user.
Branch Promotion Risks
Vulnerable schema changes can be promoted to production.
Fix: Use Deploy Requests with approval for production changes.
Connection String Exposure
PlanetScale credentials grant full database access.
Fix: Store in environment variables. Rotate if exposed.
SQL Injection
String concatenation in queries enables injection.
Fix: Use parameterized queries with ? placeholders.
Shared Infrastructure
Free tier runs on shared resources.
Fix: Use production tier for compliance workloads.
What We Check
Connection Security
Check connection string handling.
Query Security
Analyze queries for injection risks.
Access Controls
Review database access patterns.
App Security
Check application-level security.

Enter your PlanetScale application URL. Our scanner automatically detects your tech stack and configures the appropriate security checks for PlanetScale.
Automated Analysis
We scan for exposed secrets, security headers, authentication issues, database misconfigurations, and PlanetScale-specific vulnerabilities. The scan typically completes in 15-20 minutes.
Get Actionable Results
Receive a detailed report with prioritized vulnerabilities, severity ratings, and step-by-step remediation guidance with code examples specific to PlanetScale.
Common Questions About PlanetScale Security
What vulnerabilities are most common in PlanetScale apps?
The top finding classes in PlanetScale apps: no row level security; branch promotion risks; connection string exposure. Of those, connection string exposure is the most frequent critical-impact issue — it typically exposes the full dataset in a single query.
What does a VAS scan of a PlanetScale app check?
The scan probes your deployed app for the specific findings above: connection security, query security, access controls, app security. It actually attempts each vulnerability class (not just header inspection) and reports results with severity + fix for each.
Is running a scan safe for production?
Yes. The scanner uses read-only probes against public endpoints — no data modification, no destructive tests. Scans typically finish in 15–20 minutes and will not impact application availability.
Remediation Playbook for PlanetScale
Priority-ordered fixes for the specific findings we see in PlanetScale apps. Critical items close data-exposure gaps; high items prevent compromise; medium items reduce attack surface. Applies to apps using a managed backend — the dominant PlanetScale stack.
1. No Row Level Security
Why it matters: MySQL/Vitess doesn't have RLS—must implement in application.
How to close it: Build access control in application layer. Filter all queries by user.
2. Branch Promotion Risks
Why it matters: Vulnerable schema changes can be promoted to production.
How to close it: Use Deploy Requests with approval for production changes.
3. Connection String Exposure
Why it matters: PlanetScale credentials grant full database access.
How to close it: Store in environment variables. Rotate if exposed.
4. SQL Injection
Why it matters: String concatenation in queries enables injection.
How to close it: Use parameterized queries with ? placeholders.
5. Shared Infrastructure
Why it matters: Free tier runs on shared resources.
How to close it: Use production tier for compliance workloads.
Verify the fixes stuck
Run a VAS scan after applying each fix to confirm the gap is actually closed. "I applied the fix" is not evidence — the fix may have been partial, reverted, or not deployed. Re-scanning gives you proof, and a record for compliance if you ever need it.
Secure Your PlanetScale App
Don't let vulnerabilities compromise your hard work. Security issues in PlanetScale applications can lead to data breaches, unauthorized access, and damaged user trust. The average data breach costs startups between $120,000 and $1.24 million.
Run a Starter Scan in minutes — just $9. Scan before you launch and deploy with confidence knowing your application meets security best practices.
