Source: amazon-inspector (afcd41ab1e378f4c7d767acb2b9e9199a4276e125d6e84aba3627bf37c879f24) facewareretargeter 9.9.9 ships a 2-line stub module and a setup.py whose install_requires declares a single dependency, `tracer-batch-stream-chain`, sourced from a direct https URL (`https://artifacts.vacsdk.com/pypi/tracer_batch_stream_chain-9.9.9.tar.gz`) rather than a PyPI version range. On `pip install facewareretargeter`, pip fetches that tarball from the non-PyPI host and executes its setup.py / build backend on the installer's machine, with no version pin, no hash, and no integrity check. The host is not a known Python index and is unrelated to any declared repository or homepage, so whoever controls `artifacts.vacsdk.com` can deliver arbitrary code to every installer at any time. The package name resembles a plausible internal/private tool and uses an implausibly high version (9.9.9), which is the dependency-confusion shape…

# Patch Next advisory brief: mal-2026-18110

Advisory: Malicious code in facewareretargeter (PyPI)
IDs: mal-2026-18110
Record: https://patchnext.com/advisories/mal-2026-18110 (revision 1, source checked 4 Nov 2026, 06:20 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI facewareretargeter: affected >= 9.9.9, <= 9.9.9

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

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on facewareretargeter.
- 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://osv.dev/vulnerability/MAL-2026-18110 (OSV record MAL-2026-18110 lists affected ranges: PyPI facewareretargeter >=9.9.9 <=9.9.9)
