    How to Secure v0.dev

    Step-by-step guide to securing your v0.dev generated components. Learn how to protect against common vulnerabilities and launch with confidence.

    v0.dev Security Context

    v0.dev generates shadcn/ui React components. While generally secure, AI-generated components should be reviewed for XSS vulnerabilities, proper input handling, and secure API integrations before use in production.

    Security Checklist

    1

    Review generated React components

    Critical

    v0 generates shadcn/ui components - review for XSS vulnerabilities, especially dangerouslySetInnerHTML usage.

    2

    Sanitize user inputs

    Critical

    Add input validation to any forms or user-interactive components.

    3

    Secure API integrations

    Critical

    If connecting to APIs, ensure keys are stored in environment variables, not in component code.

    4

    Review component props

    Critical

    Ensure props don't expose sensitive data or allow injection attacks.

    5

    Audit third-party dependencies

    Critical

    Check that shadcn/ui and other dependencies are up to date.

    6

    Configure CSP headers

    Set Content-Security-Policy headers when deploying.

    7

    Test responsive layouts

    Verify no information is exposed in different viewport sizes.

    8

    Review event handlers

    Ensure onClick and other handlers don't expose sensitive operations.

    9

    Validate state management

    Check that sensitive data isn't stored in client-side state inappropriately.

    10

    Test with React DevTools

    Verify component state doesn't expose sensitive information.

    11

    Review accessibility

    Ensure ARIA attributes don't leak sensitive information.

    12

    Enable strict mode

    Use React strict mode to catch potential issues.

    13

    Test error boundaries

    Ensure errors don't expose sensitive component data.

    14

    Review localStorage usage

    Check that sensitive data isn't stored in localStorage.

    15

    Audit inline styles

    Ensure inline styles don't enable CSS injection.

    16
