Summary
Duplicate Advisory: NLTK: Corpus Reader Sandbox Bypass
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-3gq4-3j92-5w49. This link is maintained to preserve external references.

Original Description

NLTK versions before 3.10.3 contain a path sandbox bypass vulnerability in corpus-reader constructors that allows attackers to read files outside the intended data root. Attackers can supply arbitrary corpus root paths to LinThesaurusCorpusReader and PanLexLiteCorpusReader constructors to access filesystem content and SQLite databases outside the pathsec sandbox boundary.
