📋 Description

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-3hhw-38pf-pxj6. This link is maintained to preserve external references.

Original Description

nltk versions before 3.10.2 contain a symlink-based arbitrary file read vulnerability in IPIPANCorpusReader methods that bypass nltk.pathsec validation entirely. Attackers can place a symlink in the corpus root directory and read arbitrary files accessible to the process by calling channels(), domains(), categories(), or fileids() methods with the symlink filename.

🎯 Affected products1

  • pip/nltk:>= 3.10.0, < 3.10.2
