Echo: nltk: security update to 3.10.3

low Tenable Self-Hosted Container Security Plugin ID 461343

Description

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

 - NLTK 3.9.4 through 3.10.2 contains a path traversal vulnerability in CrubadanCorpusReader.
 _load_lang_ngrams joins the corpus root with crubadan_code, the column-0 value read from the corpus
 table.txt mapping file, and opens the result with the builtin open() rather than the pathsec-validated
 opener, so os.path.join discards the root when that value is absolute and the read escapes the corpus
 directory without the containment check nltk.pathsec applies when ENFORCE is set. An attacker who controls
 a corpus package can disclose file contents outside the corpus root through lang_freq, limited to paths
 ending in -3grams.txt whose contents parse as token count lines. (CVE-2026-71514)

Solution

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