PostgreSQL Security Scanner
Using PostgreSQL? Ensure your RLS policies and connection security are properly configured.
Enter your deployed app's URL. Review the findings, take the suggested fixes to your coding tool, and retest after making changes.
First scan free: issue counts and one finding revealed in detail. No card required.
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
Verify role permissions.
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 check the reachable app for exposed secrets, browser protections, authentication issues and database access problems. A standard scan typically takes a few minutes; blocked requests or incomplete coverage are reported.
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 does a VAS scan of a PostgreSQL app check?
VAS checks the deployed pages, scripts and endpoints it can reach for issues including connection security, rls policies, role config, query security. The report records findings and coverage limits; it does not certify the whole app as secure.
What will I receive in the report?
Findings include severity, supporting evidence and remediation guidance. Your first scan is free, with issue counts and one finding revealed in detail. Paid report access unlocks every finding. Use Export for AI to bring available findings into your coding tool, review the proposed changes and retest.
Can a scan verify every permission and private workflow?
No. Coverage depends on reachable pages, discovered endpoints and enabled checks. Configure a test login for supported authenticated checks. Review source code and business-specific permissions separately. Zero findings does not prove an app is secure.
Does VAS change my code or database policies?
VAS provides recommendations, not automatic fixes. Adapt any suggested policy or code change to your data model, test that permitted users still have access and that other users do not, then rescan. Read checks alone cannot confirm insert, update or delete permissions.
What should I know before scanning a production app?
Only scan apps you own or have permission to test. Scan requests can trigger firewall rules, logs and rate limits. Review enabled checks, and use staging or dedicated test accounts for sensitive workflows. Active tests, where enabled, need separate care because they can make changes.
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
Rescan after deploying a fix to check whether the original finding still appears. Compare the evidence and coverage with the previous report. For permissions and private workflows, also repeat the relevant tests with authorized and unauthorized test users.
Check your PostgreSQL app
Find observable security issues in your deployed app, review the evidence and take the next steps with your coding tool.
Start with a free scan. See issue counts and one finding in detail, then decide whether you need full report access.
