Security Scan

Perform a comprehensive security analysis of the codebase.

Target: $ARGUMENTS (leave empty for full scan)

Threat Model

This CLI:

• Stores API credentials (should use system keyring)
• Makes HTTP requests to Nylas API
• Reads/writes local files
• Executes based on user input

Instructions

1. Secret Detection

# Check for hardcoded API keys
grep -rE "nyk_v0[a-zA-Z0-9_]{20,}" --include="*.go" . | grep -v "_test.go"

# Check for credential patterns
grep -rE "(api_key|password|secret|token)\s*[=:]\s*\"[^\"]+\"" --include="*.go" . | grep -v "_test.go" | grep -v "mock.go"

# Check for potential credential logging
grep -rE "fmt\.(Print|Fprint|Sprint|Log).*([Aa]pi[Kk]ey|[Pp]assword|[Ss]ecret|[Tt]oken)" --include="*.go" .

2. Sensitive File Check

# Check for sensitive files in repo
find . -name "*.env*" -o -name "*.pem" -o -name "*.key" -o -name "*credential*" -o -name "*secret*" 2>/dev/null | grep -v ".git"

# Check git history for sensitive files
git log --all --name-only --pretty=format: | grep -E "\.(env|pem|key|p12)$" | sort -u

3. Dependency Vulnerabilities

# Check for known vulnerabilities in Go modules
go list -m all
# Review any outdated or suspicious dependencies

4. Code Security Review

Check for these vulnerabilities:

Category	What to Look For
Command Injection	User input in exec.Command(), os/exec
Path Traversal	User input in file paths without sanitization
Insecure HTTP	http:// instead of https:// for APIs
Weak Crypto	MD5, SHA1 for security purposes
Error Exposure	Stack traces or internal errors exposed to users

5. Authentication & Authorization

• API keys stored securely (keyring, not plaintext)
• No credentials in command-line arguments (visible in ps)
• Tokens not logged or printed
• Secure credential input (no echo)

6. Run Automated Scans

# Run project security scan
make security

# Run Go security linter (if available)
golangci-lint run --enable gosec
