1 bug, $50,000+ in bounties, how Zendesk intentionally left a backdoor in hundreds of Fortune 500 companies

hi, i'm daniel. i'm a 15-year-old with some programming experience and i do a little bug hunting in my free time. here's the insane story of how I found a single bug that affected over half of all Fortune 500 companies:

say hello to zendesk

If you've spent some time online, you’ve probably come across Zendesk.

Zendesk is a customer service tool used by some of the world’s top companies. It’s easy to set up: you link it to your company’s support email (like [email protected]), and Zendesk starts managing incoming emails and creating tickets. You can handle these tickets yourself or have a support team do it for you. Zendesk is a billion-dollar company, trusted by big names like Cloudflare.

Personally, I’ve always found it surprising that these massive companies, worth billions, rely on third-party tools like Zendesk instead of building their own in-house ticketing systems.

This class provides an efficient and flexible way to handle batch processing of jobs in a BullMQ environment, leveraging NestJS. It ensures that jobs are processed in batches, which can be crucial for performance optimization in applications requiring bulk operations..
import {WorkerHost} from '@nestjs/bullmq';
import {Job} from 'bullmq';
export class BatchWorkerHost extends WorkerHost {
private jobBatchCreationTime: Date;
private jobBatch: Job[];
private jobBatchProcessPromise: Promise<void>;
private running: boolean = false;
private resolveJobBatchProcessPromise: () => void;
