nodejs ejs versions older than 2.5.3 is vulnerable to remote code execution due to weak input validation in ejs.renderFile() function

DISPUTED ejs v3.1.9 is vulnerable to server-side template injection. If the ejs file is controllable, template injection can be implemented through the configuration settings of the closeDelimiter parameter. NOTE: this is disputed by the vendor because the render function is not intended to be used with untrusted input.

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.
