Upgrade ch.qos.logback:logback-core to version 1.5.19 or higher.
Overview
ch.qos.logback:logback-core is a logback-core module.
Affected versions of this package are vulnerable to External Initialization of Trusted Variables or Data Stores via the conditional processing of the logback.xml configuration file when both the Janino library and Spring Framework are present on the class path. An attacker can execute arbitrary code by compromising an existing configuration file or injecting a malicious environment variable before program execution. This is only exploitable if the attacker has write access to a configuration file or can set a malicious environment variable.
