Vulnerability Details

log4js-node is a port of log4js to node.js. In affected versions default file permissions for log files created by the file, fileSync and dateFile appenders are world-readable (in unix). This could cause problems if log files contain sensitive information. This would affect any users that have not supplied their own permissions for the files via the mode parameter in the config. Users are advised to update.
