Echo: nltk: security update to 3.10.3

high Tenable Self-Hosted Container Security Plugin ID 460806

Description

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

 - NLTK versions before 3.10.3 fail to use validated absolute paths when invoking the Graphviz dot binary in
 dependencygraph.dot2img and AlignedSent._repr_svg_, allowing attackers to execute arbitrary code by
 placing a malicious dot binary in the search path or current working directory. Attackers can exploit
 bare-name binary resolution on Windows via the current working directory or on Unix-like systems via
 relative PATH entries to execute their binary instead of the legitimate Graphviz tool. (CVE-2026-78680)

Solution

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