Discovers and exploits mass assignment (autobinding) in REST APIs by injecting unexpected or hidden parameters (e.g. role, isAdmin, plan) into create/update requests, using Burp Suite Intruder, Arjun, and param-miner to find bindable fields on ORM-backed endpoints (Rails, Django, Laravel, Spring). Use when testing REST APIs for privilege escalation or authorization bypass via unintended parameter binding.

Put this measurement in your README
A badge carrying how many listings this index holds from the repository and how many pass every static structural check. It reads from this index every time somebody loads your page, so it changes when the measurement changes and there is nothing to keep up to date. Free, no account, and the value is not something you or we can set by hand.
[](https://skillworks.kynth.studio/?q=mukul975%2FAnthropic-Cybersecurity-Skills)Would rather not hotlink us? Every badge is also served in shields.io’s endpoint schema, so shields renders the image and your readers never talk to our domain:
Published by Toolproof, the masthead over this index and eight others. The method behind the number is at toolproof.kynth.studio/methodology, and the whole thing is readable as JSON with no key at /api.
