PHP Site Pen-Test Challenge

i have a php website and i need a security tester this is like bug bounty if anyone breaks my admin panel and get access i wil give 5-10k Rs prize to him i will show him the full code of site then he had to try

Scope
• Focus area: the admin panel is the only target in scope.
• Typical attack vectors I’m concerned about include SQL injection, cross-site scripting (XSS) and broken authentication, but you’re free to explore any weakness you can demonstrate.

What I’ll provide
• Full PHP source code, database schema and a staging URL.
• Temporary credentials with limited privileges so you can move around the public side of the site.
• A private channel for quick questions during the test window.

What I need back
1. A step-by-step proof of exploit that reliably grants admin privileges.
2. A concise technical report explaining root cause and practical remediation steps.
3. No disruption to live users—testing must be confined to the staging environment I supply.

If you’re confident in your penetration-testing skills and comfortable working under a bounty model, I’m ready to share the repo and get started right away.
