Description Adam Mariš 2016-06-16 10:42:29 UTC 
It was found that node-cli insecurely uses the lock_file and log_file. Both of these are temporary, but it allows the starting user to overwrite any file they have access to.

lock_file = '/tmp/' + cli.app + '.pid',
log_file = '/tmp/' + cli.app + '.log';
