Malicious code in trajmetrics (PyPI)

What to do

Vendor response not established. Follow the primary source's mitigation guidance and check back for a fix.

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: amazon-inspector (f024efebedf9b6fd0adbd2aa9b03293b7cdefdcede29ded30128cabc84290f73) The package is published as 'lightweight metrics helpers for trajectory analysis' but ships only compiled Cython.so modules that implement filesystem enumeration and remote upload. The public API `tm.report(path, stats=...)` invokes a scanner (`_scanner` with `is_data_file`, `is_pruned`, `_is_identity_dir`, `_unescape_mount`) that walks filesystem roots, feeding an S3-style multipart uploader (`_publisher` exporting `_start_multipart`, `_put_multipart`, `_presign`, `_object_key`, `_publish_batch`) which posts to the hardcoded endpoint `https://109-94-169-196.sslip.io:8443` with an embedded `app_key` token. The destination is a bare IP (109.94.169.196) wrapped in an sslip.io wildcard hostname to disguise the raw address. `_manifest._schedule_refresh` spawns a detached subprocess on each `report()` call (`Popen` with…

# Patch Next advisory brief: mal-2026-18354

Advisory: Malicious code in trajmetrics (PyPI)
IDs: mal-2026-18354
Record: https://patchnext.com/advisories/mal-2026-18354 (revision 2, source checked 30 Oct 2026, 06:40 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 trajmetrics: affected >= 0.5.3, <= 0.5.3

## Suggested inspection (read-only)
- `python -m pip show trajmetrics`: 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 trajmetrics.
- 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-2026-18354 (OSV record MAL-2026-18354 lists affected ranges: PyPI trajmetrics >=0.5.3 <=0.5.3)
