5. Fix suggestion: If you have ideas for fixing the vulnerability
6. Contact: Your preferred contact method for follow-up

• Acknowledgment: We will acknowledge receipt of your report within 48 hours
• Assessment: We will assess the vulnerability and determine its severity
• Timeline: We will provide an estimated timeline for fixing the vulnerability
• Updates: We will keep you informed of progress throughout the process
• Credit: We will credit you for the discovery (unless you prefer to remain anonymous)

• High vulnerabilities: Fix within 14 days
• Medium vulnerabilities: Fix within 30 days
• Low vulnerabilities: Fix within 60 days

LogXide is designed with security in mind:

1. Memory Safety: Written in Rust to prevent memory-related vulnerabilities
2. Input Validation: All inputs are validated and sanitized
3. Minimal Dependencies: Limited external dependencies to reduce attack surface
4. Secure Defaults: Secure configuration by default
5. No Network Access: Core logging functionality doesn't require network access

While LogXide is designed to be secure, be aware of these potential concerns:

• Risk: Malicious input in log messages could lead to log injection attacks
• Mitigation: Validate and sanitize all log inputs
• Example:

  # Bad: Direct user input
  logger.info(f"User logged in: {user_input}")
  
  # Good: Sanitized input
  logger.info("User logged in: %s", sanitize(user_input))

• Risk: Sensitive information in log messages could be exposed
• Mitigation: Avoid logging sensitive data like passwords, API keys, personal information
• Example:

  # Bad: Logging sensitive data
  logger.info(f"Password: {password}")
  
  # Good: Logging without sensitive data
  logger.info("Authentication successful for user: %s", username)

• Risk: Log files with incorrect permissions could expose sensitive information
• Mitigation: Ensure log files have appropriate permissions (e.g., 600 or 640)
• Note: LogXide doesn't manage file permissions directly; this is the responsibility of the application

• Risk: Excessive logging could lead to disk space exhaustion or performance issues
• Mitigation: Implement rate limiting and log rotation
• Example:

  # Be careful with loops and error conditions
  for item in large_list:
      try:
          process(item)
      except Exception:
          logger.error("Failed to process item: %s", item)  # Could flood logs

• Risk: User-controlled format strings could lead to vulnerabilities
• Mitigation: Never use user input directly as format strings
• Example:

  # Bad: User-controlled format string
  logger.info(user_format_string % data)
  
  # Good: Safe logging
  logger.info("User action: %s", user_action)

import re

def sanitize_log_input(input_string):
    """Remove potentially dangerous characters from log input."""
    # Remove control characters and non-printable characters
    return re.sub(r'[\x00-\x1f\x7f-\x9f]', '', str(input_string))

# Usage
logger.info("User input: %s", sanitize_log_input(user_input))

# Use structured logging to separate data from format
logger.info("User action", extra={
    'user_id': user_id,
    'action': action,
    'timestamp': timestamp
})

# Use appropriate log levels
logger.debug("Detailed debugging info")      # Development only
logger.info("General information")           # Production safe
logger.warning("Warning condition")          # Attention needed
logger.error("Error condition")              # Requires action
logger.critical("Critical condition")        # Immediate action required

# Create a filter to remove sensitive data
class SensitiveDataFilter:
    def filter(self, record):
        # Remove or mask sensitive data
        if hasattr(record, 'msg'):
            record.msg = re.sub(r'password=\w+', 'password=***', record.msg)
        return True

# Apply filter to logger
logger.addFilter(SensitiveDataFilter())

LogXide includes security-focused tests:

1. Input Validation Tests: Test handling of malicious inputs
2. Memory Safety Tests: Rust's memory safety prevents many vulnerabilities
3. Fuzzing: Regular fuzzing to find edge cases
4. Static Analysis: Code analysis to identify potential issues

LogXide minimizes external dependencies:

• Runtime Dependencies: None (only Python standard library)
• Build Dependencies: Carefully vetted (PyO3, Tokio, Chrono)
• Security Audits: Regular security audits of dependencies

When we fix security vulnerabilities:

1. Private Fix: We develop and test the fix privately
2. Coordinated Disclosure: We coordinate with the reporter
3. Public Advisory: We publish a security advisory
4. CVE Assignment: We request CVE assignment if applicable
5. Patch Release: We release a patch with the fix
