Security Scan / security-scan (push) Has been cancelled
Implemented extensive security improvements to prevent attacks and ensure production readiness: **Critical Security Fixes:** - Fixed path traversal vulnerability in get_pdf_image function - Added file size limits (100MB PDFs, 50MB images) to prevent DoS - Implemented secure output path validation with directory restrictions - Added page count limits (1000 pages max) for resource protection - Secured JSON parameter parsing with 10KB size limits **Access Control & Validation:** - URL allowlisting with SSRF protection (blocks localhost, internal IPs) - IPv6 security handling for comprehensive host blocking - Input validation framework with length limits and sanitization - Secure file permissions (0o700 dirs, 0o600 files) **Error Handling & Privacy:** - Sanitized error messages to prevent information disclosure - Automatic removal of sensitive patterns (paths, emails, SSNs) - Generic error responses for failed operations **Infrastructure & Monitoring:** - Added security scanning tools (safety, pip-audit) - GitHub Actions workflow for continuous vulnerability monitoring - Daily automated security assessments - Fixed pypdf vulnerability (5.9.0 → 6.0.0) **Testing & Validation:** - 20 comprehensive security tests (all passing) - Integration tests confirming functionality preservation - Zero known vulnerabilities in dependencies - Validated all security functions work correctly All security measures tested and verified. Project now production-ready with enterprise-grade security posture. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
