Description

This security bulletin contains information about 1 vulnerability.


1) Input validation error (CVE-ID: CVE-2026-1225)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:L/AC:H/AT:P/PR:H/UI:N/VC:L/VI:L/VA:L/SC:L/SI:L/SA:L/E:U/U:Clear


The vulnerability allows a local privileged user to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input. A local privileged user can 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.
