CyberRota Analysis
AI-GeneratedThe Stanza NLP library prior to version 1.12.2 is vulnerable to arbitrary code execution due to improper handling of attacker-controlled model files during the loading process. This flaw allows a malicious actor to execute arbitrary code by crafting a malicious .pt file, posing significant risks to applications utilizing this library for natural language processing tasks. Organizations using Stanza for NLP should prioritize upgrading to version 1.12.2 or later to mitigate this high-severity vulnerability.

Original NVD Description
Stanza is a Stanford NLP Python library for tokenization, sentence segmentation, NER, and parsing of many human languages. Prior to 1.12.2, Stanza model loaders such as stanza.models.common.pretrain.Pretrain.load() attempt torch.load(..., weights_only=True) but fall back to torch.load(..., weights_only=False) on attacker-controllable pickle.UnpicklingError, allowing a malicious .pt pretrain or model file to execute arbitrary pickle code when a Stanza NLP pipeline loads it. This issue is fixed in version 1.12.2.
