You know when it’s coming from Gareth Heyes you did something right! XSS WAF bypass using multi-character HTML entities like >⃒ or <⃒ which are interpreted by the server respectively as 'less than' and greater than symbols (plus some other unicode character). Shout out also to @therceman!
Add parameters like $lookup, $unionWith, and $match to your wordlist for testing. Any errors or hits on these might give a hint to a potential NoSQL injection. Shout out to Soroush Dalili for this research!
Exploiting unsanitised user inputs in Django ORM filter methods to exfiltrate sensitive data. Shout out to @elttam for this HOT research! 🔥 #infosec #bugbounty #bugbounties #cybersecurity #criticalthinking #CTBBpodcast #bugbountytips #bugbountyhunters #hacking #hackers
iOS auth flaw ala evanconnelly and mrtuxracer 1. Install malicious app and register victim's scheme 2. User approves the evil app to login with attacker.com (ofc, why not) 3. Web view opens, attacker forces redirect to vuln auth flow for victim app w/ prompt=none 4. Auth code sent to attackers…

Unwrapping wrappers to get to the real function that is actually being triggered with Frans Rosen's postMessage-tracker!
Here's an interesting one folks! Frans discovered state validation was happening before you acquire the code so you can get the victim to use your state instead.
Episode 78: In this episode of Critical Thinking - Bug Bounty Podcast we’re talking about writing reports. We share some tips that we’ve learned, and discuss ways that AI can (and can’t) help with that process. We also talk about the benefit of incorporating tools like Fabric, Loom, and ShareX.…
That time Frans Rosen roasted Justin live on the pod when discussing Frans' sick poster of Google's /etc/passwd file!
Another great example of the importance of gadget hunting as well as bug hunting!
Found a gadget where X-Forwarded-For was blocked, but x-forwarded-for was allowed. Tools like ffuf actually auto-capitalize headers so you would easily miss this without manually testing!

Some seriously good research dropped on the pod last week. Shout out to Piotr Bazydło and The Zero Day Initiative for this crazy XXE in Microsoft Sharepoint!
Joel's tip of the week: Keep it simple. It's easy to overcomplicate things. Sometimes all you need is a simple match and replace instead of some next level regex!
H4R3L's "Cookie XSS" affecting almost every Zoom page and subdomain demonstrates the effectiveness of experimenting with escape characters in cookie values.
