Summary

Fix critical severity security issue in helpers/odmOptionsToJson.py.

Vulnerability

Field Value
ID V-001
Severity CRITICAL
Scanner multi_agent_ai
Rule V-001
File helpers/odmOptionsToJson.py:37
Assessment Likely exploitable

Description: The Python helper script helpers/odmOptionsToJson.py uses sys.argv[2] directly in sys.path.append() and load_source() calls without any sanitization or validation. An attacker who can control the arguments passed to this script when invoked from Node.js via child_process could inject shell metacharacters or point to malicious Python files to execute arbitrary code.

Evidence

Exploitation scenario: An attacker who can control the arguments passed to odmOptionsToJson.py execution (e.g., via the 'options' parameter in task creation that influences project-path) could supply a path like.

Scanner confirmation: multi_agent_ai rule V-001 flagged this pattern.

Production code: This file is in the production codebase, not test-only code.

Threat Model Context

This is a web service - vulnerabilities in request handlers are directly exploitable by remote attackers.

Thanks, but this isn't a vulnerability. The second argument is config.odm_path, the server's own ODM install directory. It's set once at startup from the --odm_path flag or the config file (config.js:109) and never changes. Task options don't reach this script, and the only caller (libs/odmRunner.js:142) already quotes the value. Anyone who can change --odm_path controls the process command line and needs no help from this script.

The realpath/isdir checks don't close anything, so I'm closing this. A clearer error on a bad --odm_path would be fine as a separate hygiene change with an accurate description.

Thanks for the clarification. I traced the caller in libs/odmRunner.js and agree that config.odm_path is server-side configuration and is not derived from task options, so the reported remote exploitation path does not apply.

I’ll withdraw the vulnerability claim. The validation change can instead be treated as defensive configuration hygiene, since the helper currently assumes that the configured path exists and contains the expected opendm modules.

Thanks for pointing out the actual data flow.
