CVE-2026-1225

ACE vulnerability in configuration file processing by QOS.CH logback-core up to and including version 1.5.24 in Java applications, allows an attacker to instantiate classes already present on the class path by compromising an existing logback configuration file.

The instantiation of a potentially malicious Java class requires that said class is present on the user's class-path. In addition, the attacker must have write access to a configuration file. However, after successful instantiation, the instance is very likely to be discarded with no further ado.

Code Review

This pull request updates the ch.qos.logback:logback-core dependency from version 1.5.21 to 1.5.25. This is an important security update to address a vulnerability in logback. The change in java-showcase/gapic-showcase/pom.xml correctly updates the slf4j2-logback.version property. The change is correct and necessary, and I approve it.
