Echo: nltk: security update to 3.10.3

high Tenable Cloud Security Plugin ID 457875

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- NLTK versions before 3.10.3 contain a path traversal vulnerability in corpus readers that reopen root-
derived paths using built-in open() instead of nltk.pathsec.open(), allowing symlinks to escape trusted
roots. Attackers who stage symlinked corpus files under a trusted data root can disclose outside-root
content through normal corpus reader methods like channels(), domains(), and synonyms(). (CVE-2026-79676)

Solution

Update the nltk library and its related packages to version 3.10.3 or later.
