Overview
nltk is a Natural Language Toolkit (NLTK) is a Python package for natural language processing.
Affected versions of this package are vulnerable to Remote Code Execution (RCE) through the integrated data package download functionality. An attacker with control over the NLTK data index can execute arbitrary code by supplying pickled Python code within untrusted packages and trick a user into loading the malicious pickle.
Some packages found to be vulnerable if compromised are averaged_perceptron_tagger, punkt, maxent_ne_chunker, help/tagsets, and maxent_treebank_pos_tagger.
