GraphQL isn’t just an API to deliver our payloads. Often, its implementations are what actually cause them. To see what bugs it can lead to, studied disclosed bug bounty reports. IDORs, privescs, DoS, CSRFs, SQLis - it's all there. Enjoy!

If your GraphQL testing stops at introspection and ID swapping, you’re missing out. SQLi, CSRF, caching bugs, race conditions, WebSocket bypasses - it’s all there. I studies 90 real reports to find what actually works.

Having them as separate products allows me to dedicate a few weeks straight to them instead of just spending a few days here and there. This way, I can focus better without dealing with the context switching. I might even add a video layer to them.

Future content I do plan to create more products in the future. For example, I’d like to create courses about code review, Burp, or advanced SSRF techniques.

Because of this, I missed a few issues last year, and I’m really sorry to all the members for that.

Bug Bounty Reports Explained @gregxsunday.bsky.social · 21/02/2025
I remember coming back from h1-702 feeling fired up to hunt more bugs right after the event, but instead, I had to create content during that time. The context switching was also pretty frustrating and sometimes made me waste two or three days on work that should’ve only taken one.

Personal reasons With me starting to attend LHE and AWC in-person hacking events, it was hard to keep up with writing articles regularly. During the events, I wanted to focus 100% on bug bounty, which meant I either had to write the articles before the event or catch up afterward.

Bug Bounty Reports Explained @gregxsunday.bsky.social · 21/02/2025
Therefore, I feel it makes more sense for both you and me to separate certain materials into different products and sell access to them with a one-time fee.

Bug Bounty Reports Explained @gregxsunday.bsky.social · 21/02/2025
For example, I feel like the value of all the case studies is worth much more than the yearly BBRE Premium, which gives you access to all of them.

Bug Bounty Reports Explained @gregxsunday.bsky.social · 21/02/2025
The subscription model creates a situation where new members gain access to dozens of articles that might not be their priority, and at the same time, because it is a subscription, it becomes difficult for me to justify a higher price.

Bug Bounty Reports Explained @gregxsunday.bsky.social · 21/02/2025
Business reasons Most members have joined BBRE Premium for the Case Studies or for one of the series, such as the OAuth course.
100
Bug Bounty Reports Explained @gregxsunday.bsky.social · 21/02/2025
For example, the price of just the case study package will be $299 so if you don’t join now for $128, you may regret it later.
100
Bug Bounty Reports Explained @gregxsunday.bsky.social · 21/02/2025
Later this year, it will be possible to purchase access to case studies, the OAuth course or the Devtools course as separate products. However, their price will be significantly higher than the current price of $128.

For non-members - this is the good opportunity to join for a lifetime access to the entire BBRE Premium archive before it’s gone forever on February 28th

Bug Bounty Reports Explained @gregxsunday.bsky.social · 21/02/2025
Current members, don't worry — you'll have a lifetime access with no charge.
