WebSocket DoS via fragment count bypass — CVE-2026-12151

GHSA-vxpw-j846-p89q · CWE-400, CWE-770 Fix: 32dbf0b3 websocket: limit the number of fragments in a message (also c5ed7875 handle empty fragments and stream limits)

A malicious WebSocket server can stream a large number of small or empty continuation frames. Undici enforced a limit on cumulative payload size but did not limit the number of fragments per message, leading to unbounded memory growth and denial of service.

• Affected: applications using new WebSocket(...) or WebSocketStream against untrusted endpoints.
• Workaround: none — upgrade is required.

WebSocket DoS via cumulative fragment bypass — CVE-2026-9675

GHSA-38rv-x7px-6hhq · CWE-400, CWE-770 Fix: b4c287b3 fix(websocket): enforce max payload size across fragments

Undici validated the size of individual frames but did not track cumulative size across a fragmented message. An attacker could send many small fragments that each pass per-frame validation but collectively exceed the configured limit, causing memory exhaustion. This is a regression introduced in 8.1.0 (the

Minor Changes

• #9539 f0615fd Thanks @​ematipico! - Added a new reporter called concise. When --reporter=concise is passed the commands format, lint, check and ci, the diagnostics are printed in a compact manner:

  ! index.ts:2:10: lint/correctness/noUnusedImports: Several of these imports are unused.
  ! main.ts:9:7: lint/correctness/noUnusedVariables: This variable f is unused.
  × index.ts:8:5: lint/suspicious/noImplicitAnyLet: This variable implicitly has the any type.
  × main.ts:2:10: lint/suspicious/noRedeclare: Shouldn't redeclare 'z'. Consider to delete it or rename it.
  

• #9495 2056b23 Thanks @​aviraldua93! - Added the useKeyWithClickEvents a11y lint rule for HTML files (.html, .vue, .svelte, .astro). This is a port of the existing JSX rule. The rule enforces that elements with an onclick handler also have at least one keyboard event handler (onkeydown, onkeyup, or onkeypress) to ensure keyboard accessibility.

  Inherently keyboard-accessible elements (<a>, <button>, <input>, <select>, <textarea>, <option>) are excluded, as are elements hidden from assistive technologies (aria-hidden) or with role="presentation" / role="none".

  <!-- Invalid: no keyboard handler -->
  <div onclick="handleClick()">Click me</div>
  <!-- Valid: has keyboard handler -->
  <div onclick="handleClick()" onkeydown="handleKeyDown()">Click me</div>
  <!-- Valid: inherently keyboard-accessible -->
  <button onclick="handleClick()">Submit</button>

• #9152 9ec8500 Thanks @​ematipico! - Added new nursery lint rule noUndeclaredClasses for HTML, JSX, and SFC files (Vue, Astro, Svelte). The rule detects CSS class names used in class="..." (or className) attributes that are not defined in any <style> block or linked stylesheet reachable from the file.

  <!-- .typo is used but never defined -->
  <html>
    <head>
      <style>
        .button {
          color: blue;
        }
      </style>
    </head>
    <body>
      <div class="button typo"></div>
    </body>
  </html>

• #9152 9ec8500 Thanks @​ematipico! - Added new nursery lint rule noUnusedClasses for CSS. The rule detects CSS class selectors that are never referenced in any HTML or JSX file that imports the stylesheet. This is a project-domain rule that requires the module graph.
