Pull Request Overview
This PR addresses a security vulnerability (log injection) by sanitizing user input before logging. The fix prevents malicious line breaks in user input from corrupting log entries or affecting log parsing.
Key Changes
- Sanitizes user input by removing carriage returns and newlines before logging
- Implements the fix directly in the REPL module where user input is processed

Consider using a more comprehensive sanitization approach. The current fix only removes \r and \n, but other control characters like \t (tab) could also be problematic for log parsing. Consider using user_input.replace('\r', '').replace('\n', '').replace('\t', ' ') or a regex approach to handle all control characters.

To prevent log injection, all user input that is logged must be sanitized to remove line breaks and other characters that could adversely affect log parsing or display. The best practice is to replace
\rand\nwith empty strings before including user data in a log entry. This change should be performed just before logging on line 33—either by using a cleaned variable or directly inline. No additional dependencies are required for this simple sanitization. Only the line that constructs the log message with user input needs to be changed.Suggested fixes powered by Copilot Autofix.
