    Give every meaningful image an alt, aria-label, or aria-labelledby.

    : error in React projects
    No autofix

    Put readable text inside every link.

    : warning in React projects
    No autofix

    Only use aria-* attributes that actually exist.

    : error in React projects
    No autofix
  • react-doctor/aria-proptypes

    Give each aria-* attribute the kind of value it expects.

    : error in React projects
    No autofix

    No autofix
  • react-doctor/aria-unsupported-elements

    Do not put role or aria-* on reserved HTML elements.

    : error in React projects
    No autofix
  • react-doctor/artifact-env-leak

    Treat public env prefixes as publication, not secrecy; keep secret env vars server-only and rebuild after rotating leaked keys.

    : error in React projects
    No autofix
  • react-doctor/artifact-secret-leak

    Remove the secret from client bundles/static assets, rotate it, and route privileged service calls through server-only code.

    : error in React projects
    No autofix
  • react-doctor/auth-token-in-web-storage

    Don't persist auth tokens (JWTs, access/refresh tokens, secrets) in localStorage/sessionStorage; they're readable by any XSS. Use an HttpOnly cookie set by the server.

    : warning in React projects
    No autofix
  • react-doctor/autocomplete-valid

    Use a valid autofill token in autoComplete so browsers can fill the right field reliably.

    : warning in React projects
    No autofix
  • react-doctor/base-ui-dialog-popup-requires-title

    : warning in React projects
    No autofix
  • react-doctor/base-ui-field-requires-label

    Give every Field.Root that wraps a Field.Control a Field.Label (visually hidden when the design shows no label) or name the control directly with aria-label.

    : warning in React projects
    No autofix
  • react-doctor/base-ui-tabs-tab-requires-list

    Render each Base UI Tabs.Tab inside Tabs.List so the tablist role and arrow-key focus handling cover every tab.

    : warning in React projects
    No autofix
  • react-doctor/build-pipeline-secret-boundary

    Run dependency installs with scripts disabled before exposing secrets, isolate untrusted build code, and move signing/deploy authority into a narrow privileged step.

    : warning in React projects
    No autofix
  • react-doctor/button-has-type

    Set an explicit button type so plain buttons do not submit forms by accident: type="button", "submit", or "reset".

    : warning in React projects
    No autofix
  • react-doctor/checked-requires-onchange-or-readonly

    Add onChange, readOnly, or defaultChecked so React knows whether the checkbox is editable, display-only, or uncontrolled.

    : warning in React projects
    No autofix
  • react-doctor/class-component-missing-component-will-unmount-teardown

    Release listeners and timers acquired in componentDidMount/constructor by adding a componentWillUnmount that removes them (or use MobX disposeOnUnmount).

    : warning in React projects
    No autofix

    : warning in React projects
    No autofix

    : error in React projects
    No autofix
  • react-doctor/control-has-associated-label

    Give every interactive control a label screen readers can read.

    : warning in React projects
    No autofix
  • react-doctor/cors-cookie-trust-risk

    Keep auth cookies host-only and HttpOnly, avoid credentialed CORS for less-trusted docs/vendor origins, and isolate documentation domains from app sessions.

    : warning in React projects
    No autofix
  • react-doctor/dangerous-html-sink

    Prefer rendering structured React nodes. If HTML is required, sanitize with a well-reviewed sanitizer and keep the trust boundary close to the sink.

    : warning in React projects
    No autofix
  • react-doctor/debounce-no-cleanup

    A debounced/throttled callback holds a pending timer that still fires after unmount, so add useEffect(() => () => debounced.cancel(), [debounced]) to cancel the trailing invocation when the component tears down.

    : warning in React projects
    No autofix
  • react-doctor/dialog-has-accessible-name

    Give every <dialog> / role="dialog" an accessible name with aria-label or aria-labelledby (referencing the dialog's title element).

    Pass the same callback binding and capture flag to addEventListener and removeEventListener, or abort the registration's local AbortController during cleanup.

    : error in React projects
    No autofix
