<h2>Logback 1.5.34</h2>
<p><strong>2026-06-01 Release of logback version 1.5.34</strong></p>
<p>• In case certain StackTraceElement values returned by the
Throwable.getStackTrace method are null, StackTraceElementProxy
substitutes a dummy instance instead of throwing an
IllegalArgumentException. This resolves [issues <a
href="https://redirect.github.com/qos-ch/logback/issues/1040">#1040</a>](<a
href="https://redirect.github.com/qos-ch/logback/issues/1040">qos-ch/logback#1040</a>),
reported by Naotsugu Kobayashi.</p>
<p>• HardenedObjectInputStream will now throw an InvalidClassException
during deserialization attempts of Proxy classes. This change addresses
potential deserialization whitelist bypass vulnerability reported by <a
href="https://github.com/york-shen">York Shen</a> and registered as <a
href="https://www.cve.org/cverecord?id=CVE-2026-10532">CVE-2026-10532</a>.</p>
<p>• A bitwise identical binary of this version can be reproduced by
building from source code at commit
e62272ac152469aec1ede056c3c7d0d7314e7bfe associated with the tag
v_1.5.34. This release was built using Java &quot;21&quot; 2023-10-17
LTS build 21.0.1.+12-LTS-29 under Linux Debian 11.6.</p>
