Retool Security Scanner
Building internal tools with Retool? Ensure your data connections and queries are secure.
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.
Retool Security Considerations
Retool makes development fast, but AI-generated code often skips security best practices:
- !Resource connection security
- !Query parameter injection
- !Access control configuration
- !Audit logging requirements
Where Security Breaks in Retool Apps
Built on Supabase (Postgres + RLS), Retool applications share a recognizable fingerprint, which means attackers and automated scanners find them the same way every time. Based on real vulnerability patterns in Retool deployments, the breakdown is 1 critical-impact issue, 1 high-impact, and 2 medium-or-lower.
Resource connection security
A common failure mode in Retool applications: resource connection security. Left unchecked, this can lead to data exposure, unauthorized access, or service abuse.
Fix: 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.
Query parameter injection
A common failure mode in Retool applications: query parameter injection. Left unchecked, this can lead to data exposure, unauthorized access, or service abuse.
Fix: Use parameterized queries, sanitize all user input, and render dynamic content with framework escaping (React JSX, not dangerouslySetInnerHTML).
Access control configuration
A common failure mode in Retool applications: access control configuration. Left unchecked, this can lead to data exposure, unauthorized access, or service abuse.
Fix: Enable Row Level Security (Supabase) or Security Rules (Firebase) on every table. For custom backends, enforce authorization at the query layer — never client-side.
Audit logging requirements
A common failure mode in Retool applications: audit logging requirements. Left unchecked, this can lead to data exposure, unauthorized access, or service abuse.
Fix: Enable audit logging for all data access and admin operations. Retain logs per your compliance requirements (7 years for SOX, indefinite for some PCI scenarios).

What You'll Get
Why Retool Apps Need Security Scanning
Retool helps build internal tools quickly, but those tools often connect to sensitive data sources. Security configuration is critical.
vas helps ensure your Retool applications properly protect sensitive data and connections.
How Retool Security Scanning Works
Submit Your URL
Enter your Retool application URL. Our scanner automatically detects your tech stack and configures the appropriate security checks for Retool.
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 Retool.
Common Questions About Retool Security
What does a VAS scan of a Retool app check?
VAS checks the deployed pages, scripts and endpoints it can reach for issues including resources, queries, access control, audit logs. 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 Retool
Priority-ordered fixes for the specific findings we see in Retool apps. Critical items close data-exposure gaps; high items prevent compromise; medium items reduce attack surface. Applies to apps using Supabase (Postgres + RLS), the dominant Retool stack.
1. Resource connection security
Why it matters: A common failure mode in Retool applications: resource connection security. Left unchecked, this can lead to data exposure, unauthorized access, or service abuse.
How to close it: 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.
2. Query parameter injection
Why it matters: A common failure mode in Retool applications: query parameter injection. Left unchecked, this can lead to data exposure, unauthorized access, or service abuse.
How to close it: Use parameterized queries, sanitize all user input, and render dynamic content with framework escaping (React JSX, not dangerouslySetInnerHTML).
3. Access control configuration
Why it matters: A common failure mode in Retool applications: access control configuration. Left unchecked, this can lead to data exposure, unauthorized access, or service abuse.
How to close it: Enable Row Level Security (Supabase) or Security Rules (Firebase) on every table. For custom backends, enforce authorization at the query layer — never client-side.
4. Audit logging requirements

How to close it: Enable audit logging for all data access and admin operations. Retain logs per your compliance requirements (7 years for SOX, indefinite for some PCI scenarios).
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.
