PostgreSQL Security Scanner
Using PostgreSQL? Ensure your RLS policies and connection security are properly configured.
Our automated security scanner analyzes your Postgres application for vulnerabilities, misconfigurations, and exposed secrets. Get a comprehensive security report in minutes, not days.
PostgreSQL Security Considerations
PostgreSQL makes development fast, but AI-generated code often skips security best practices:
- !Connection string exposure
- !Missing Row Level Security
- !Weak role configuration
- !SQL injection vulnerabilities
Where Security Breaks in PostgreSQL Apps
Built on Postgres, PostgreSQL applications share a recognizable fingerprint — which means attackers and automated scanners find them the same way every time. Based on real vulnerability patterns in PostgreSQL deployments, the breakdown is 3 critical-impact issues, 2 high-impact, and 0 medium-or-lower.
RLS Not Enabled
Tables without Row Level Security are fully accessible.
Fix: ALTER TABLE name ENABLE ROW LEVEL SECURITY on all tables.
SQL Injection
String concatenation in queries enables injection attacks.
Fix: Use parameterized queries ($1, $2). Never concatenate user input.
Superuser Application Access
Connecting as postgres user grants unlimited database access.
Fix: Create limited roles for applications. Disable postgres user.
Missing SSL/TLS
Unencrypted connections expose data in transit.
Fix: Require SSL: sslmode=verify-full in connection strings.
Permissive pg_hba.conf
Host-based auth allowing connections from anywhere.
Fix: Configure pg_hba.conf to restrict hosts and require SSL.
What We Check
Connection Security
Review connection handling.
RLS Policies
Check Row Level Security.
Role Config

Query Security
Scan for SQL injection.
What You'll Get
Why PostgreSQL Apps Need Security Scanning
PostgreSQL is a powerful database with enterprise security features. However, these features must be properly configured to be effective.
VAS helps verify your PostgreSQL-backed application has proper RLS policies and secure connection handling.
How PostgreSQL Security Scanning Works
Submit Your URL
Enter your Postgres application URL. Our scanner automatically detects your tech stack and configures the appropriate security checks for PostgreSQL.
Automated Analysis
We scan for exposed secrets, security headers, authentication issues, database misconfigurations, and PostgreSQL-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 PostgreSQL.
Common Questions About PostgreSQL Security
What vulnerabilities are most common in PostgreSQL apps?
The top finding classes in PostgreSQL apps: rls not enabled; sql injection; superuser application access. Of those, rls not enabled is the most frequent critical-impact issue — it typically exposes the full dataset in a single query.
What does a VAS scan of a PostgreSQL app check?
The scan probes your deployed app for the specific findings above: connection security, rls policies, role config, query 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 PostgreSQL
Priority-ordered fixes for the specific findings we see in PostgreSQL apps. Critical items close data-exposure gaps; high items prevent compromise; medium items reduce attack surface. Applies to apps using Postgres — the dominant PostgreSQL stack.
1. RLS Not Enabled
Why it matters: Tables without Row Level Security are fully accessible.
How to close it: ALTER TABLE name ENABLE ROW LEVEL SECURITY on all tables.
2. SQL Injection
Why it matters: String concatenation in queries enables injection attacks.
How to close it: Use parameterized queries ($1, $2). Never concatenate user input.
3. Superuser Application Access
Why it matters: Connecting as postgres user grants unlimited database access.
How to close it: Create limited roles for applications. Disable postgres user.
4. Missing SSL/TLS
Why it matters: Unencrypted connections expose data in transit.
How to close it: Require SSL: sslmode=verify-full in connection strings.
5. Permissive pg_hba.conf
Why it matters: Host-based auth allowing connections from anywhere.
How to close it: Configure pg_hba.conf to restrict hosts and require SSL.
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 PostgreSQL App
Don't let vulnerabilities compromise your hard work. Security issues in PostgreSQL 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.
