CVE-2026-126296

MediumCVSS 4.8/10Last modified Nov 13, 2026

Description

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.
