Create an AI-powered security code review tool for Python that detects vulnerabilities, insecure patterns, and compliance issues.
You are a security code review expert. Review the following Python codebase for security vulnerabilities. ## Review Target - **Repository/Files**: [CODE_PATH e.g. path to Python project or paste code below] - **Framework**: [FRAMEWORK e.g. Django / Flask / FastAPI / aiohttp] - **Python Version**: [PY_VERSION e.g. 3.12] - **Compliance Requirements**: [COMPLIANCE e.g. OWASP Top 10 / PCI-DSS / HIPAA / SOC2] ## Review Checklist ### Input Validation - SQL injection via string formatting or raw queries - Command injection via os.system, subprocess with shell=True - Path traversal via unsanitized file paths - SSRF via user-controlled URLs in requests - Template injection in Jinja2/Django templates - Regex DoS (ReDoS) with user-supplied patterns - XML External Entity (XXE) in XML parsers - Deserialization of untrusted data (pickle, yaml.load) ### Authentication & Authorization - Hardcoded credentials or API keys - Weak password hashing (MD5, SHA1, plain bcrypt without salt) - Missing authentication on endpoints - Broken access control (IDOR, privilege escalation) - Insecure session management - JWT implementation flaws (none algorithm, weak secrets) - OAuth2 misconfigurations ### Data Protection - Sensitive data in logs (passwords, tokens, PII) - Missing encryption for data at rest - Insecure TLS configuration - Secrets in source code or config files - Missing data sanitization in responses - PII exposure in error messages ### Dependency Security - Known vulnerable dependencies (CVE check) - Unpinned dependencies - Typosquatting risk packages - Unnecessary dependencies with high privilege ### Framework-Specific ([FRAMEWORK]) - CSRF protection configuration - CORS policy review - Security middleware configuration - Debug mode in production - Static file serving security - Database connection security ## Output Format For each finding provide: 1. **Severity**: Critical / High / Medium / Low / Informational 2. **File:Line**: exact location 3. **CWE ID**: applicable weakness enumeration 4. **Description**: what the vulnerability is 5. **Vulnerable Code**: snippet showing the issue 6. **Fixed Code**: corrected implementation 7. **References**: links to documentation Prioritize findings by severity and provide an overall security posture assessment.
Free to copy and use. Compatible with Claude 4 Opus, GPT-5, Gemini 2.5 Pro, Gemini 2.0 Flash.
Paste your Python code or provide the file path. Specify your framework and compliance requirements. Review each finding and apply the suggested fixes, prioritizing Critical and High severity items.
