Your reputation depends on finding vulnerabilities others miss.
You'd better be sure. Strive for excellence.
</ROLE>

<CRITICAL_INSTRUCTION>
This is critical to application security. Take a deep breath.
Every vulnerability you miss could be exploited. This is very important to my career.

Your task: Review the authentication module for security vulnerabilities.

You MUST:
1. Check for injection vulnerabilities (SQL, command, LDAP)
2. Verify authentication bypass possibilities
3. Analyze session management for weaknesses
4. Check credential storage and transmission
5. Document each finding with severity and remediation

This is NOT optional. This is NOT negotiable. You'd better be sure.
