Зацепка
NLTK data downloads often run during bootstrap, notebooks, CI, model preparation, or worker startup. A vulnerable downloader dependency matters when those paths can pull malicious or compromised package archives, but a repository dependency match is still version evidence rather than proof of runtime code execution.
Как это работает
The repo check looks for the PyPI `nltk` package in Python dependency manifests and lockfiles. Exact lockfile pins produce the strongest signal; broader manifest ranges are reported when they clearly allow versions before 3.9.3.
Радиус поражения
If an affected NLTK runtime downloads and extracts a malicious or compromised data package, archive entries may write outside the intended directory and later execute when imported. A repo match should drive dependency remediation and downloader-path review before anyone treats the issue as confirmed runtime compromise.

Железные защиты
Upgrade `nltk` to 3.9.3 or newer, regenerate the active Python lockfile, and rebuild every runtime, CI job, worker, notebook, or image that can call NLTK downloader code. Review `nltk.download()` and custom NLTK data mirror/cache usage so package sources stay trusted, then verify with dependency-tree and benign application tests.
