I'd like to work on this security hardening task. As a software engineer with experience in application security, backend systems, and secure API design, I can perform a thorough review of NotifyChain's codebase and implement necessary protections.

I will audit authentication flows, API authorization boundaries, and input validation paths to identify potential vulnerabilities. I’ll address confirmed issues with secure fixes, add tests where needed, and document findings, remediation steps, and security considerations in a review report.

The PR will include the security improvements, validation results, documentation, and follow the required branch workflow using security/hardening-audit.

Hey team,

I’ll take this on. I can run a comprehensive security audit on NotifyChain to identify and fix potential vulnerabilities. I will create the security/hardening-audit branch, review our authentication flows and API endpoint permission guards, and harden input validation across the system. Finally, I'll compile and submit a clear security review report detailing the findings and resolutions to ensure no critical issues remain.

Mind assigning this to me? Thanks
