Subject: CVE-2025-54813: Apache Log4cxx: Improper escaping with JSONLayout
Severity: moderate
Affected versions:
- Apache Log4cxx 0.11.0 before 1.5.0
Description:
Improper Output Neutralization for Logs vulnerability in Apache Log4cxx.
When using JSONLayout, not all payload bytes are properly escaped. If an attacker-supplied message contains certain non-printable characters, these will be passed along in the message and written out as part of the JSON message. This may prevent applications that consume these logs from correctly interpreting the information within them.
This issue affects Apache Log4cxx: before 1.5.0.
Users are recommended to upgrade to version 1.5.0, which fixes the issue.
