MONAI vulnerable to OS command injection

GHSA-rghg-q7wp-9767

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (monai 1.6.0), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Comment from JPCERT/CC We are submitting the report again as we have yet to receive any responses from you after submitting it on February 5 and March 11. It would be greatly appreciated if you could send us a message after confirming it so that we can follow up the case by email. Summary MONAI vulnerable to OS command injection. Details This library concatenates user-controlled values (YAML's "datasetnameorid" or part of "CLI/kwargs") without quoting or validation. Since this string is passed to subprocess with shell=True, shell metacharacters (e.g., Windows: & / Linux: ;) are interpreted. As a result, arbitrary commands can be concatenated and executed. Therefore, the reporter identifies this as CWE-78 (OS Command Injection). The victim needs to load a crafted YAML file in the code that launches training/validation jobs based on the configuration (YAML/arguments). There are no other constraints. PoC Verified on Windows. Load a modified YAML file with crafted "datasetnameorid" as…

# Patch Next advisory brief: GHSA-rghg-q7wp-9767

Advisory: MONAI vulnerable to OS command injection
IDs: GHSA-rghg-q7wp-9767
Record: https://patchnext.com/advisories/ghsa-rghg-q7wp-9767 (revision 1, source checked 26 Oct 2026, 13:50 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: monai 1.6.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI monai: affected < 1.6.0; fixed in 1.6.0

## Suggested inspection (read-only)
- `python -m pip show monai`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on monai.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-rghg-q7wp-9767 (GitHub-reviewed advisory GHSA-rghg-q7wp-9767 lists affected ranges: PyPI monai >=0 <1.6.0)
