CVE-2026-126296

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