Audit Areas
1. Access Control
- Are permissions following least-privilege?
- Are there overly permissive grants?
- Is the public/anon role properly restricted?
2. Row Level Security (PostgreSQL)
- Is RLS enabled on all user-facing tables?
- Are policies correctly scoped?
- Are there policies that always evaluate to true?
- Do policies reference trusted claims only (not user metadata)?
3. Data Exposure
- Are sensitive columns (email, phone, SSN) protected?
- Are auth tables (auth.users) exposed through the API?
- Are there views that bypass security?
4. Function Security
- Do functions have fixed search_path?
- Are SECURITY DEFINER functions necessary?
- Is there SQL injection risk in dynamic SQL?
5. Encryption
- Are sensitive columns encrypted at rest?
- Is the connection using TLS?
For each finding, provide:
- Severity: CRITICAL / HIGH / MEDIUM / LOW
- Description: What the issue is
- Remediation: How to fix it with specific SQL
