<h2>v6.27.0</h2>
<h1>⚠️ Security Release</h1>
<p>This release line addresses <strong>4 security
advisories</strong>.</p>
<blockquote>
<p><strong>Action required:</strong> Upgrade to <strong>undici
6.27.0</strong> or later.</p>
<pre lang="sh"><code>npm install undici@^6.27.0
</code></pre>
</blockquote>
<blockquote>
<p><strong>Note on patched version:</strong> the v6 fixes shipped in
<strong>v6.27.0</strong>, not <code>6.26.0</code>
— <code>v6.26.0</code> contains only the chunked-EOF fix (<a
href="https://redirect.github.com/nodejs/undici/issues/5308">#5308</a>)
and the version bump, none
of the security fixes below.</p>
</blockquote>
<p>The v6 line is <strong>not</strong> affected by the SOCKS5 advisories
(GHSA-vmh5-mc38-953g,
GHSA-hm92-r4w5-c3mj), the shared-cache disclosure (GHSA-pr7r-676h-xcf6),
or the
8.x-only WebSocket regression (GHSA-38rv-x7px-6hhq).</p>

<h2>High severity</h2>
<h3>WebSocket DoS via fragment count bypass — CVE-2026-12151</h3>
<p><strong><a
href="https://github.com/nodejs/undici/security/advisories/GHSA-vxpw-j846-p89q">GHSA-vxpw-j846-p89q</a></strong>
· CWE-400, CWE-770
<strong>Fix:</strong> <a
href="https://github.com/nodejs/undici/commit/b7f252e7"><code>b7f252e7</code></a>
<em>Backport WebSocket maxPayloadSize fixes</em> (<a
href="https://redirect.github.com/nodejs/undici/pull/5423">#5423</a>,
backported to v6 in <a
href="https://redirect.github.com/nodejs/undici/pull/5428">#5428</a>)</p>
<p>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 <em>number</em> of fragments per message, leading to
unbounded memory
growth and denial of service. All releases from 6.17.0 onward are
affected.</p>
<ul>
<li><strong>Affected:</strong> applications using <code>new
WebSocket(...)</code> or <code>WebSocketStream</code>
against untrusted endpoints.</li>
<li><strong>Workaround:</strong> none — upgrade is required.</li>
</ul>
<hr />
<h2>Moderate severity</h2>
<h3>HTTP header injection via Set-Cookie percent-decoding —
CVE-2026-9679</h3>
