CVE-2026-13006

A flaw was found in logback-core, a logging framework for Java applications. This vulnerability allows an attacker with existing privileges and write access to a configuration file, or the ability to inject a malicious environment variable, to execute arbitrary code. This can be achieved by compromising an existing logback configuration file or by injecting an environment variable before program execution, circumventing existing protections. A successful attack requires the Janino library to be present on the user's class path.
