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.
