Bypassing 403 Forbidden: Advanced Techniques for Bug Bounties

Encountering a 403 Forbidden or Access Denied error can feel like hitting a brick wall. But in bug bounties, this often means you’re one tweak away from uncovering a hidden vulnerability. Below are advanced, real-world techniques to bypass 403s, complete with secret tips, tools, and why they work.

1. HTTP Method Tampering

Why it works: Servers often enforce access controls only on common methods like GET or POST. Switching to less-used methods (PUT, PATCH, DELETE, TRACE, etc.) can bypass misconfigured rules.

Try This:

curl -X TRACE https://example.com/admin --path-as-is
