SCA: security update for stanza (GHSA-gh9r-c94j-cmp5)

high Tenable Cloud Security Plugin ID 478294

Description

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

 - Stanza is a Stanford NLP Python library for tokenization, sentence segmentation, NER, and parsing of many
 human languages. From 1.14.0 until 1.15.0, loading an attacker-supplied lemmatizer checkpoint can execute
 arbitrary code because stanza/models/lemma/trainer.py stores pos_dict as gzip-compressed pickle bytes and
 Trainer.load passes the decompressed stream to unrestricted pickle.loads. The outer torch.load call uses
 weights_only=True, but the nested bytes are treated as a primitive and are not inspected by that
 allowlist. The path is reachable during pipeline construction through a caller-influenced
 lemma_model_path, before inference begins. This issue is fixed in version 1.15.0. (CVE-2026-115878)

Solution

Update the stanza library and its related packages to version 1.15.0 or later.
