+# Security Summary - Version 1.0.5
+
+## Overview
+This document summarizes the security improvements made in version 1.0.5 of py-stats-toolkit.
+
+## Security Audit Results
+
+### Initial State (Before Updates)
+- **Total vulnerabilities found**: 23 known vulnerabilities in 10 packages
+- **Audit tool**: pip-audit v2.10.0
+- **Audit date**: December 10, 2025
+
+### Critical Vulnerabilities Fixed
+
+#### 1. Cryptography Package (CVE-2023-50782, CVE-2024-0727, PYSEC-2024-225, GHSA-h4gh-qq45-vh27)
+- **Previous version**: 41.0.7
+- **Updated to**: >=44.0.0
+- **Impact**: Fixed multiple critical security vulnerabilities in cryptographic operations
+- **Severity**: HIGH
+
+#### 2. Jinja2 (CVE-2024-22195, CVE-2024-34064, CVE-2024-56326, CVE-2024-56201, CVE-2025-27516)
+- **System package** (not directly in requirements, but via dependencies)
+- **Impact**: Fixed template injection and XSS vulnerabilities
+- **Severity**: HIGH
+
+#### 3. Requests (CVE-2024-35195, CVE-2024-47081)
+- **System package** (not directly in requirements, but via dependencies)
+- **Impact**: Fixed HTTP header injection and other security issues
+- **Severity**: MEDIUM
+
+#### 4. Urllib3 (CVE-2024-37891, CVE-2025-50181, CVE-2025-66418, CVE-2025-66471)
+- **System package** (not directly in requirements, but via dependencies)
+- **Impact**: Fixed HTTP request smuggling and proxy authentication issues
+- **Severity**: MEDIUM to HIGH
+
+#### 5. Setuptools (CVE-2024-6345, PYSEC-2025-49)
+- **System package**
+- **Impact**: Fixed arbitrary code execution vulnerability
+- **Severity**: HIGH
+
+#### 6. Other Fixed Vulnerabilities
+- certifi (PYSEC-2024-230)
+- configobj (CVE-2023-26112)
+- idna (PYSEC-2024-60)
+- pip (CVE-2025-8869)
+- twisted (CVE-2024-41671, PYSEC-2024-75)
+
+### Final State (After Updates)
+
+#### Vulnerabilities Remaining: 1
+
+**ecdsa v0.19.1 - CVE-2024-23342**
+- **Type**: Timing attack on P-256 curve (Minerva attack)
+- **Affected operations**: ECDSA signatures, key generation, ECDH operations
+- **Unaffected**: ECDSA signature verification
+- **Status**: NO FIX AVAILABLE - Considered out of scope by maintainers
+- **Risk assessment**: 
+  - This vulnerability requires physical access or network proximity to perform timing attacks
+  - Does not affect normal usage of the library
+  - The python-ecdsa project considers side-channel attacks out of their security scope
+  - Used by python-jose for JWT operations (not directly exposed in our API)
+- **Mitigation**: Use hardware security modules (HSM) for production cryptographic operations if concerned about timing attacks

+
+## Security Best Practices Implemented
+
+1. **Automated Security Scanning**: Added pip-audit to development dependencies for continuous security monitoring
+2. **Regular Updates**: All packages updated to their latest stable and secure versions
+3. **Minimum Version Requirements**: Updated all version constraints to ensure secure versions are always installed
+4. **Python Version Update**: Dropped Python 3.8 support (EOL October 2024), now requiring Python 3.9+
+5. **Dependency Cleanup**: Removed duplicate entries to prevent version conflicts
+
+## Verification
+
+All updates have been verified through:
+- ✅ pip-audit security scan (reduced from 23 to 1 vulnerability)
+- ✅ GitHub Advisory Database check (all main dependencies secure)
+- ✅ CodeQL static analysis (no code vulnerabilities detected)
+- ✅ Full test suite (12/12 tests passing)
+- ✅ Package build verification (successful)
+
+## Recommendations for Users
+
+1. **Update immediately**: Run `pip install --upgrade py-stats-toolkit` to get security fixes
+2. **Python version**: Ensure you're using Python 3.9 or later
+3. **Regular updates**: Keep dependencies up to date with `pip install --upgrade -r requirements.txt`
+4. **Security scanning**: Run `pip-audit` regularly in your projects to detect vulnerabilities
+5. **HSM usage**: For production cryptographic operations, consider using hardware security modules
