PlanetScale Security

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.

HIGH

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.

HIGH

Branch Promotion Risks

Vulnerable schema changes can be promoted to production.

Fix: Use Deploy Requests with approval for production changes.

CRITICAL

Connection String Exposure

PlanetScale credentials grant full database access.

Fix: Store in environment variables. Rotate if exposed.

CRITICAL

SQL Injection

String concatenation in queries enables injection.

Fix: Use parameterized queries with ? placeholders.

LOW

Shared Infrastructure

Free tier runs on shared resources.

Fix: Use production tier for compliance workloads.

Why PlanetScale Apps Need Security Scanning

PlanetScale offers serverless MySQL with powerful branching workflows. Understanding its security model helps you protect your data.

VAS scans applications using PlanetScale to ensure secure database access patterns.

How PlanetScale Security Scanning Works

1

Submit Your URL

Enter your PlanetScale application URL. Our scanner automatically detects your tech stack and configures the appropriate security checks for PlanetScale.

2

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.

3

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.
