<p>An update that solves seven vulnerabilities can now be installed.</p>
<h2>Description:</h2>
<p>This update for nodejs20 fixes the following issues:</p>
<p>Update to version 20.20.2.</p>
<ul>
<li>CVE-2026-21717: trivially predictable hash collisions due to flaw in V8's string hashing mechanism allows for
performance degradation via a crafted request (bsc#1260494).</li>
<li>CVE-2026-21716: incomplete fix for CVE-2024-36137 allows promise-based FileHandle methods to be used to modify file
permissions and ownership on already-open file descriptors (bsc#1260462).</li>
<li>CVE-2026-21715: flaw in the Permission Model filesystem enforcement allows for file existence disclosure and
filesystem path enumeration via <code>fs.realpathSync.native()</code> (bsc#1260482).</li>
<li>CVE-2026-21714: memory leak in Node.js HTTP/2 server allows for resource exhaustion via <code>WINDOW_UPDATE</code> frames sent
on stream 0 (bsc#1260480).</li>
<li>CVE-2026-21713: timing side-channel due to flaw in Node.js HMAC verification allows for discovery of HMAC values and
potential MAC forgery (bsc#1260463).</li>
<li>CVE-2026-21710: uncaught <code>TypeError</code> when handling HTTP requests allows for a process crash via requests with a
header named <code>__proto__</code> when the application accesses <code>req.headersDistinct</code> (bsc#1260455).</li>
<li>CVE-2026-21637: flaw in TLS error handling allows for resource exhaustion and crash when <code>pskCallback</code> or
<code>ALPNCallback</code> are in use (bsc#1256576).</li>
</ul>
