NVD Description

Note: Versions mentioned in the description apply only to the upstream nltk package and not the nltk package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

NLTK through 3.10.3 contains a path traversal vulnerability in WekaClassifier that allows attackers to bypass nltk.pathsec containment by supplying unvalidated model paths. Attackers controlling the model_filename or model argument can make the weka JVM write files via -d or probe files via -l outside allowed data roots.
