Convex Security Risks
Know the risks before you deploy. Understanding Convex security vulnerabilities is the first step to building secure applications.
Instant results. See which risks apply to you.
Every platform has security risks—the key is understanding them. Convex applications face specific vulnerabilities that, if left unaddressed, can lead to data breaches, financial loss, and reputational damage. This guide covers the real risks and practical mitigations.
Convex Security Risks
#1Unauthenticated Query Access
Convex queries are public by default. Without explicit auth checks, anyone can read your data.
Enforce email verification, minimum password requirements, and rate limiting on auth endpoints. Test auth flows as unauthenticated and cross-user to verify access controls.
#2Unprotected Mutations
Mutations without identity verification allow unauthenticated data manipulation.
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.
#3Secrets in Action Functions
Actions calling external APIs may have secrets accessible if function access controls aren't configured.
Enable Row Level Security (Supabase) or Security Rules (Firebase) on every table. For custom backends, enforce authorization at the query layer — never client-side.
#4Missing Argument Validation
Queries and mutations accepting user input without validation are susceptible to injection.
Use parameterized queries, sanitize all user input, and render dynamic content with framework escaping (React JSX, not dangerouslySetInnerHTML).
Who Is Most At Risk?
Real user data at risk of exposure
Financial and PCI compliance implications
Exposed keys lead to abuse and charges
May contain sensitive business data
Limited data but teaches insecure patterns
How to Reduce These Risks
Most Convex security risks are preventable with proper configuration. The majority of vulnerabilities we find are not complex exploits—they're missing settings and exposed credentials that automated scanning catches instantly.
- Run automated security scans before every deployment
- Configure database access controls from day one
- Store all secrets in environment variables
- Enable email verification and strong password requirements
- Add security headers to your hosting configuration
- Review AI-generated code for security before accepting

What are the biggest security risks with Convex?
The most critical Convex risks are: exposed credentials/API keys, missing database access controls, and weak authentication. These account for the majority of real-world breaches in Convex applications.
How likely is my Convex app to be attacked?
If your app is public on the internet, it's being scanned constantly. Automated tools probe for common vulnerabilities within minutes of deployment. The question isn't if you'll be scanned, but whether attackers will find anything exploitable.
Can I use Convex safely for production?
Yes, with proper security configuration. Convex provides the tools for secure applications—you need to use them correctly. Configure access controls, manage secrets properly, add security headers, and scan before launch.
How do I reduce security risks in my Convex app?
Start with a security scan to identify current vulnerabilities. Then: 1) Fix critical issues first (exposed secrets, missing access controls), 2) Enable email verification and strong passwords, 3) Add security headers, 4) Set up continuous scanning.
Are Convex security risks different from other platforms?
The core risks are similar across vibe coding platforms—they all have exposed secrets, missing access controls, and auth weaknesses. Convex-specific risks relate to its particular tech stack and default configurations.
