CVE-2026-1225 (GCVE-0-2026-1225)

Vulnerability from cvelistv5 – Published: 2026-01-22 09:24 – Updated: 2026-01-22 14:14

Title

Malicious logback.xml configuration file allows instantiation of arbitrary classes

Summary

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.
