Overview
CVE-2026-1225 is a known-severity vulnerability. It was published on January 22, 2026.
Technical description
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.
