4 Security Issues Documented
Common vulnerabilities found in Appwrite applications
High Severity Issues
Overprivileged API Keys
highServer-side API keys leaked into frontend bundles give attackers admin access.
Third-party API abuse (OpenAI quota drained, Stripe charges made), lateral access to connected services, and disclosure of internal systems.
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.
Move all secrets server-side (environment variables, serverless functions). Rotate any keys previously in frontend code. Audit bundles for leftover credentials before each deploy.
Unprotected Storage Buckets
highFile storage buckets without permissions expose uploaded documents to anyone.
Attack surface expansion. In combination with other findings, enables data exposure, account compromise, or service abuse.
Attempt to upload an executable file (.sh, .php, .exe) or a file with a mismatched Content-Type. If accepted, the upload validation is weak.
Validate file types and sizes server-side. Store uploads in a bucket with strict access policies. Scan files for malware before serving.
Missing Function Authentication
highFunctions deployed without execution permissions allow unauthenticated triggers.
Account takeover of legitimate users. Attackers gain full access to victim accounts and any data/actions those accounts permit.
Attempt 20+ login requests with the same username in under 60 seconds. If all complete without rate limiting or lockout, the issue is present.
Enforce email verification, minimum password requirements, and rate limiting on auth endpoints. Test auth flows as unauthenticated and cross-user to verify access controls.
Medium Severity Issues
Permissive Collection Rules
mediumCollections with 'any' role permissions allow unauthenticated users to read or delete documents.
Account takeover of legitimate users. Attackers gain full access to victim accounts and any data/actions those accounts permit.
Attempt 20+ login requests with the same username in under 60 seconds. If all complete without rate limiting or lockout, the issue is present.
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

Get Starter ScanFrequently Asked Questions
What are the most common Appwrite 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 Appwrite applications.
How do I find security issues in my Appwrite 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 Appwrite security issues fixable?
Yes, nearly all Appwrite 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 Appwrite 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 Appwrite have built-in security?
Appwrite 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.
