SCA: security update for nltk (GHSA-p4gq-832x-fm9v)
high Tenable Self-Hosted Container Security Plugin ID 444813
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- NLTK (Natural Language Toolkit) is a suite of open source Python modules, data sets, and tutorials
supporting research and development in Natural Language Processing. Prior to 3.10.0-rc1, nltk.data.load()
in NLTK is vulnerable to path traversal via URL-encoded path separators and traversal segments when using
the nltk: URL scheme. The unsafe-path regex check is performed before url2pathname() decodes the %xx
sequences (a classic decode-after-check / TOCTOU-style flaw), allowing an attacker to bypass the
protection documented in NLTK's SECURITY.md and read arbitrary files from the filesystem. While literal
traversal strings such as ../../../etc/passwd are correctly blocked, encoded variants such as
%2fetc%2fpasswd, %2e%2e%2f..., and ..%2f..%2f slip past the regex and are subsequently decoded into a real
filesystem path. This vulnerability is fixed in 3.10.0-rc1. (CVE-2026-54293)
Solution
Update the nltk library and its related packages to version 3.10.0 or later.See Also
