4 Security Issues Documented

Common vulnerabilities found in Wix Harmony applications

1 Critical2 High1 Medium

Critical Security Issues

Broken Access Control in Custom Pages

critical

AI-generated member-only pages may fail to properly restrict access at the data layer.

Impact

Complete database exposure — attackers can read, modify, or delete all user data. For Wix Harmony apps that handle PII or payment data, this becomes a reportable breach (GDPR 72-hour notification).

How to Detect

Run a read query as an unauthenticated client in the Firebase Emulator Suite. If any data is returned without auth, Security Rules are permissive.

How to 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.

High Severity Issues

Exposed Wix Data Collections

high

AI-generated code may query backend collections without proper permission checks, exposing user data.

Impact

Unreviewed insecure code reaches production. The vulnerability class depends on what the AI generated; the common outcome is data exposure or auth bypass.

How to Detect

Run a VAS scan against the deployed Wix Harmony app URL — automated detection is the fastest and most reliable path.

How to Fix

Require human review for security-sensitive code (auth, data access, secrets). Run automated security scanning on every AI-generated change before merging.

Insecure Third-Party Integrations

high

AI-generated API calls may embed third-party credentials in client-side page code.

Impact

Third-party API abuse (OpenAI quota drained, Stripe charges made), lateral access to connected services, and disclosure of internal systems.

How to Detect

Open the deployed app in a browser, view-source on the main bundle, grep for patterns like `sk-`, `sk_live_`, `eyJ`, `AKIA`, `AIza`. A single match is a confirmed exposure.

How to Fix

Move all secrets server-side (environment variables, serverless functions). Rotate any keys previously in frontend code. Audit bundles for leftover credentials before each deploy.

Medium Severity Issues

Misconfigured Wix Permissions

medium

Harmony-generated Velo code may override default Wix collection permissions to make data publicly readable.

Impact

Attack surface expansion. In combination with other findings, enables data exposure, account compromise, or service abuse.

How to Detect

Run a VAS scan against the deployed Wix Harmony app URL — automated detection is the fastest and most reliable path.

How to 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.

How to Prevent These Issues

  • Run automated security scans before every deployment
  • Configure database access controls (RLS/Security Rules) first
  • Store all secrets in environment variables, never in code
  • Enable email verification and strong password policies
  • Add security headers to your hosting configuration
  • Review AI-generated code for security before accepting

Frequently Asked Questions

What are the most common Wix Harmony security issues?

The most common issues are: exposed API keys/secrets, missing database access controls (RLS or Security Rules), weak authentication configuration, and missing security headers. These account for over 80% of vulnerabilities in Wix Harmony applications.

How do I find security issues in my Wix Harmony app?

Run a VAS security scan for automated detection of common vulnerabilities. Manually check: database access controls, search code for hardcoded secrets, verify authentication settings, and test security headers. VAS catches all of these automatically.

Are Wix Harmony security issues fixable?

Yes, nearly all Wix Harmony security issues are configuration problems with straightforward fixes. Missing RLS, exposed secrets, weak auth—all have clear remediation steps. Most fixes take under an hour to implement.

How quickly can Wix Harmony security issues be exploited?

Exposed databases and API keys can be discovered within minutes using automated scanners. Attackers actively scan for common patterns. This is why security configuration must happen before deployment, not after.

Does Wix Harmony have built-in security?

Wix Harmony provides security features, but they require configuration. Security isn't automatic—you must enable database access controls, manage secrets properly, configure auth settings, and add security headers. The tools exist; you must use them.
