CVE-2026-94091 Details
Description
A weakness has been identified in piskvorky gensim up to 4.4.0. The impacted element is the function Load of the file gensim/utils.py of the component Model Loader. This manipulation of the argument fname causes deserialization. It is possible to initiate the attack remotely. The exploit has been made available to the public and could be used for attacks. Maintainer closed #3663 same-day with no comment, PR, or fix; repo's last push (2025-11-01) predates the report, so the unsafe pickle.load in SaveLoad.load remains unguarded at develop HEAD.
A remote code execution vulnerability exists in Gensim versions up to 4.4.0. The issue arises in the Model Loader component, specifically within the Load function of gensim/utils.py. The vulnerability is triggered by the argument fname, which, when manipulated, leads to unsafe deserialization. This flaw allows for arbitrary code execution, as the deserialization occurs without any safeguards, enabling an attacker to execute malicious payloads remotely.
