Security researcher. I find and report vulnerabilities in open source software, mostly authentication and authorization bugs in Go web backends. I also do bug bounty work.
| CVE | Project | Class | Lab + writeup |
|---|---|---|---|
| CVE-2026-44166 | PocketBase | OAuth2 account pre-hijacking | repo |
| CVE-2026-28699 | Gitea | OAuth2 scope bypass via HTTP Basic auth | repo |
Each repo has a writeup and a lab you can run. The lab pins the exact vulnerable and patched versions, scripts the attack, and prints a clear pass or fail so the difference between the two builds is obvious.
- OAuth2 and OIDC flows, and the spots where two parts of a system disagree about identity or scope
- Authentication and authorization logic in general
- Source review of Go backends
Start with the writeup in either repo and run the PoC from there.
