Security Vulnerability Scan

Automated Secret Detection

!git grep -rn "api_key\|apikey\|api-key\|secret\|password\|passwd\|token\|bearer\|private_key\|access_key\|client_secret\|auth_token" --include="*.ts" --include="*.js" --include="*.py" --include="*.go" --include="*.rs" --include="*.java" --include="*.rb" --include="*.cs" --include="*.env*" --include="*.yml" --include="*.yaml" --include="*.json" --include="*.toml" --include="*.cfg" --include="*.ini" --include="*.conf" 2>/dev/null | grep -v node_modules | grep -v .git | grep -v vendor | grep -v "\.lock" | grep -v "test" | grep -vi "example\|placeholder\|your_\|TODO\|FIXME\|change_me" | head -30

Environment Files Check

!find . -name ".env*" -not -path "*/node_modules/*" -not -path "*/.git/*" 2>/dev/null !cat .gitignore 2>/dev/null | grep -i "env\|secret\|key\|credential" || echo "WARNING: .gitignore may not exclude secret files"

Vulnerability Checklist

Scan the codebase systematically for each vulnerability class. For every finding:

• Severity: Critical / High / Medium / Low
• File path and line number
• Vulnerability type (CWE ID if known)
• Description of the risk
• Remediation steps with code

1. Injection Flaws

• SQL Injection: String concatenation in queries instead of parameterized/prepared statements
• NoSQL Injection: Unsanitized user input in MongoDB/DynamoDB queries
• Command Injection: User input passed to exec, system, os.popen, subprocess without sanitization
• LDAP Injection: Unsanitized input in LDAP queries
• Path Traversal: User input in file paths without normalization (../../../etc/passwd)
• Template Injection: User input rendered in templates without escaping (SSTI)

2. Cross-Site Scripting (XSS)

• Unescaped user input rendered in HTML
• dangerouslySetInnerHTML / v-html / |safe with user content
• Reflected XSS via URL parameters
• Stored XSS via database content rendered without sanitization
• DOM-based XSS via document.write, innerHTML, eval

3. Authentication & Authorization

• Missing authentication on sensitive endpoints
• Broken access control (IDOR — accessing other users' resources by ID)
• Missing rate limiting on login/auth endpoints
• JWT tokens without expiry or with weak signing algorithms (HS256 with weak secret)
• Session tokens in URLs or local storage
• Missing CSRF protection on state-changing operations

4. Hardcoded Secrets

• API keys, tokens, passwords in source code
• Private keys or certificates in the repository
• Database connection strings with embedded credentials
• Secret values in configuration files that should use env vars

5. Insecure Configuration

• Debug mode enabled in production configs
• Verbose error messages exposing stack traces or internals
• Open CORS policies (Access-Control-Allow-Origin: *)
• Missing security headers (CSP, HSTS, X-Frame-Options)
• Default credentials not changed
• Unnecessary ports or services exposed

6. Data Exposure

• Sensitive data in logs (passwords, tokens, PII)
• PII returned in API responses without need
• Missing encryption for data at rest or in transit
• Overly permissive file/directory permissions
• Backup files or source maps exposed in production

7. Dependency Vulnerabilities

• Check for known vulnerable dependencies using:
• npm audit / yarn audit (Node.js)
• pip audit / safety check (Python)
• go vuln check (Go)
• cargo audit (Rust)
• dotnet list package --vulnerable (.NET)

Output Format

Findings by Severity

#### Critical (exploit possible, immediate fix required) <!-- List findings -->

#### High (significant risk, fix before deploy) <!-- List findings -->

#### Medium (should be addressed in next sprint) <!-- List findings -->

#### Low (hardening recommendations) <!-- List findings -->

Security Score

Rate the overall security posture from 0 to 10 (10 = excellent, 0 = critical vulnerabilities present).

Risk Assessment

Provide a paragraph summarizing the overall security state, the most concerning patterns, and the recommended order of remediation.
