Summary
Jenkins 2.527 and earlier, LTS 2.516.2 and earlier does not restrict or transform the characters that can be inserted from user-specified content in log messages, allowing attackers able to control log message contents to insert line break characters, followed by forged log messages that may mislead administrators reviewing log output.
