Summary
NLTK before 3.10.4 Path Traversal via save_maxent_params and load_maxent_params
Details

NLTK before 3.10.4 contains a path traversal vulnerability in save_maxent_params() and load_maxent_params() that bypasses the pathsec filesystem restriction mechanism. Attackers who control the tab_dir argument can read or overwrite model parameter files outside permitted data roots, because the functions call Python's built-in open() directly.
