Remediation Suggestions
- Remove the
PORTFOLIOroute and_handle_portfolio()if portfolio management is not an intended, supported capability. - If the capability is required, bundle the implementation within this project and import a narrowly scoped function instead of executing a sibling Python script.
- Resolve the script with
os.path.realpath()and verify that it remains inside a trusted, immutable application directory. - Verify component provenance and integrity before use, such as by pinning an approved release and checking a cryptographic digest.
- Ensure the script and all parent directories are owned by a trusted account and are not writable by untrusted users or packages.
- Run portfolio functionality in a restricted subprocess or sandbox with minimal filesystem, environment, and network access.
- Use a minimal environment for any unavoidable subprocess and avoid passing unrelated secrets through inherited environment variables.
- Disable portfolio routing by default and require explicit administrative configuration to enable it.
- Check subprocess return codes and handle missing or invalid scripts securely rather than reporting unconditional success.
