Summary

A weakness has been identified in piskvorky gensim up to version 4.4.0. The impacted element is the Load function in gensim/utils.py of the Model Loader component. Manipulation of the fname argument causes deserialization. The attack can be initiated remotely, and the exploit has been made public. The maintainer closed issue #3663 same-day with no comment, and the unsafe pickle.load in SaveLoad.load remains unguarded.

Risk Assessment

A remote attacker can supply a malicious model file, leading to arbitrary code execution on the server, potentially resulting in system compromise.

Recommendation

Avoid loading untrusted model files and implement safe deserialization methods. Monitor gensim updates and consider using alternative libraries.
