Fix ARIA Label Errors in React

ARIA label errors occur when the accessible name for an interactive element is missing, empty, computed from an element that does not exist, or redundant with visible text. Common patterns include aria-label="", aria-labelledby pointing to a removed ID, and aria-label duplicating the same visible string a screen reader will already read.

The accessible name is what assistive technologies announce to users. When it is wrong, controls become unreachable in practice — even if they pass a simple axe scan.

WCAG 2.1 Success Criterion 4.1.2 (Name, Role, Value) requires every user interface component to expose a name, role, and value to assistive technology. Section 508 incorporates this criterion directly. Screen reader users navigate by name; an icon button with no name is announced as "button" and nothing else.

ARIA label bugs are the single most common automated finding in enterprise remediation audits, and they account for a large share of the Department of Justice ADA web complaints filed each year.

<button aria-label="">
  <SearchIcon />
</button>

<input type="text" aria-labelledby="missing-id" />

<a href="/cart" aria-label="cart">Cart (3)</a>

<button aria-label="Search products">
  <SearchIcon aria-hidden="true" />
</button>

<label htmlFor="q">Search</label>
<input id="q" type="text" />

<a href="/cart">
  Cart <span className="sr-only">(3 items)</span> (3)
</a>

The fixed version provides an explicit name on the icon button, replaces a broken aria-labelledby with a real <label>, and lets the visible link text be the accessible name instead of overriding it.

fixa11y detects every ARIA labeling pattern: empty values, dangling references, duplicated content, and incorrect use of aria-label on non-interactive elements. The fixer rewrites the component using semantic HTML where possible and only falls back to ARIA when the native role does not exist.

Each fix is annotated with the WCAG criterion it satisfies (4.1.2, 1.3.1, 2.4.4) so reviewers can trace the change to a specific compliance requirement.
