Supabase Audit Auth Signup

What it does

This skill enables AI agents to perform security audits on Supabase authentication signup flows. It specifically tests for vulnerabilities such as account enumeration and weak password policies during user registration processes.

When to use it

• Identifying if an application allows attackers to guess valid usernames through error message differences.
• Verifying that Supabase enforces strong password requirements during new account creation.
• Assessing the resilience of signup endpoints against brute-force or automated registration attacks.
• Validating that rate limiting is effectively configured on authentication routes.

Key capabilities

• Analyzes signup endpoint responses for information leakage regarding user existence.
• Evaluates password strength validation logic within the Supabase configuration.
• Simulates automated account creation attempts to test system defenses.

Example prompts

• "Audit the signup flow of this Supabase project to check for username enumeration vulnerabilities."
• "Run a security scan on the authentication registration endpoint to verify password policy enforcement."
• "Test the resilience of this Supabase instance against automated brute-force attacks during user signups."

Tips & gotchas

Ensure you have valid access credentials and appropriate permissions for the target Supabase project before initiating any audit. This skill is designed for authorized security testing; unauthorized scanning of production systems may violate terms of service or laws.
