Real-World Exposure
ni-measurementlink-service🐍ni-measurementlink-serviceReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
Impact
An improper access restriction in NI MeasurementLink Python services could allow an attacker on an adjacent network to reach services exposed on localhost. These services were previously thought to be unreachable outside of the node. This affects measurement plug-ins written in Python using version 1.1.0 of the ni-measurementlink-service Python package and all previous versions.
Patches
Upgrade all Python measurement plug-ins to use ni-measurementlink-service version 1.1.1 or later.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ni-measurementlink-service, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update ni-measurementlink-service to 1.1.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-4570 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
