Thank you for the encouraging response! I've completed my analysis and found
specific configuration security issues that I'm ready to address with a PR.
## Identified Configuration Security Issue:
**File**: `airflow/example_dags/example_trigger_target_dag.py` (Line 54)
- **Issue**: Example DAG demonstrates unescaped user input pattern from
`dag_run.conf` that could lead to command injection if users copy and modify
the pattern
- **Risk**: Users might create vulnerable implementations like
`bash_command=f'echo "Message: {dag_run.conf.get("message")}"'`
## Planned PR (24-48 hours):
1. **Fix**: Add proper input escaping/sanitization to the example
2. **Enhancement**: Include security comment explaining best practices for
user input handling
3. **Documentation**: Demonstrate secure pattern for future reference
## Technical Approach:
- Replace unescaped parameter usage with properly escaped version
- Add security-focused comment explaining the importance of input validation
- Maintain backward compatibility and functional intent
The fix is minimal, focused, and provides educational value for the
community. Ready to proceed with the PR once I complete the final code
validation.
