Node.js mpath module could allow a remote attacker to execute arbitrary code on the system, caused by a prototype pollution flaw. By adding or modifying properties of Object.prototype using a proto or constructor payload, an attacker could exploit this vulnerability to execute arbitrary code on the system.

A Command injection attack was found in ejs (Embedded JavaScript templates) for Node.js, which allows an attacker to execute server-side template injection in settings[view options][outputFunctionName]. This is parsed as an internal option and overwrites the outputFunctionName option with an arbitrary OS command executed upon template compilation.

A flaw was found in nodejs-netmask. Octal input data may lead to a server-side request forgery, remote file inclusion, local file inclusion, and other vulnerabilities. The highest threat from this vulnerability is to data integrity.
