Package : node-log4js
Version : 4.0.2-2+deb10u1
CVE ID : CVE-2022-21704

In node-log4js, a port of log4js in Node.js, default file permissions
for log files created by the file, fileSync, and dateFile appenders are
world-readable. 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.

For Debian 10 buster, this problem has been fixed in version
4.0.2-2+deb10u1.

We recommend that you upgrade your node-log4js packages.
