CVE-2024-39705
First published: Thu Jun 27 2024(Updated: )
Natural Language Toolkit (NLTK) could allow a remote attacker to execute arbitrary code on the system, caused by a flaw when an untrusted packages have pickled Python code, and the integrated data package download functionality is used. By sending a specially crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.
