概要

Impact

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.

Patches

Fixed by:

Released to NPM in [email protected]

Workarounds

Every version of log4js published allows passing the mode parameter to the configuration of file appenders, see the documentation for details.
