Favorite bug chain of the year:
Broken Access Control in Comment Mentions → Stored XSS → CSP bypass → Notification code execution → Domain-wide token → Tenant-wide account takeover.
Sometimes the smallest features hide the biggest bugs.
Should I write a full write-up?
Just got paid $2,000 for a single SSRF. 🩸
It started with a simple “fetch this image” endpoint.
A few requests later, I had access to internal APIs that were never meant to be exposed.
Big thanks to my mentor, @safe_mode01 , for the continuous guidance and support. 🙏
