Release notes

Sourced from ch.qos.logback:logback-classic's releases.

Logback 1.5.34

2026-06-01 Release of logback version 1.5.34

• 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 #1040](qos-ch/logback#1040), reported by Naotsugu Kobayashi.

• HardenedObjectInputStream will now throw an InvalidClassException during deserialization attempts of Proxy classes. This change addresses potential deserialization whitelist bypass vulnerability reported by York Shen and registered as CVE-2026-10532.

• 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 "21" 2023-10-17 LTS build 21.0.1.+12-LTS-29 under Linux Debian 11.6.

Logback 1.5.33

2026-05-27 Release of logback version 1.5.33

• PropertiesConfiguratorModelHandler now registers properties file URLs to the ConfigurationWatchList when scan is enabled (via local scan="true" attribute or top-level configuration scan), ensuring changes are detected and reconfiguration occurs. This problem was reported in issues/1034.

• When processing <conversionRule> elements and both class and converterClass attributes are specified, silently use the class attribute without issuing a warning. However, if the attribute values differ, a warning will be issued. This change was requested in issues/1031.

• HardenedModelInputStream will no longer accept to deserialize all classes located under the "java.lang" and "java.util" packages but a limited number of explicitly authorized classes in those packages. This potential deserialization whitelist bypass vulnerability was reported by York Shen and registered as CVE-2026-9828.

• SSL parameters for SSLSocketAppender now enable hostname verification by default. Moreover, the default protocol is now "TLSv1.2". This potential vulnerability was reported by York Shen.

• When printing the status message field, ViewStatusMessagesServletBase now escapes special characters such as "&" as character entities. This potential vulnerability was reported by York Shen.

• A bit-wise identical binary of this version can be reproduced by building from source code at commit 124e8b49b55ac34d08743a0646bd463410192647 associated with the tag v_1.5.33. Release built using Java "21" 2023-10-17 LTS build 21.0.1.+12-LTS-29 under Linux Debian 11.6.
