Do you need to file an issue?

• I have searched the existing issues and this bug is not already filed.
• My model is hosted on OpenAI or Azure. If not, please look at the "model providers" issue and don't file a new one here.
• I believe this is a legitimate bug, not just a question. If this is a question, please use the Discussions area.

Describe the issue

Graphrag currently uses nltk==3.9.1 as a dependency.
This version has a vulnerability: https://nvd.nist.gov/vuln/detail/CVE-2025-14009
The guidance is to upgrade to 3.9.3.

Looking quickly at the nltk changelog I do not see breaking changes that would affect graphrag, but happy to look more into it and open a PR.

Is there any news on this? Right now nltk 3.9.1 has three CVE's with scores of 10.0, 10.0 and 8.6. We are using this package in an AI production environment, and this is causing us some major issues regarding compliancy. From what I see it seems safe to bump NLTK from 3.9.1 to 3.9.3.

Any timeline on when this might actually be fixed?
