Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-8mgp-746c-j5xp. This link is maintained to preserve external references.

Original Description

NLTK through 3.10.3 contains a path traversal vulnerability in model-artifact APIs that bypass pathsec enforcement by using raw file operations on caller-controlled paths. Attackers can read or write files outside allowed sandbox roots through TransitionParser, AveragedPerceptron, PerceptronTagger, and maxent parameter APIs when pathsec is enabled.
