CVE-2024-10073Public exploitNetwork attack vector

Code execution via unsafe model deserialization

Published Oct 17, 2024 · Updated Oct 17, 2024

Unsafe model deserialization in flairNLP Flair 0.14.0 allows attackers to execute arbitrary code through a crafted model file. ClusteringModel.load in flair/models/clustering.py passes joblib-loaded data directly to pickle.loads, which invokes attacker-controlled pickle reducers. Exploitation requires an application or user to obtain the crafted file and pass it to the loader; resulting code runs with the Flair process's privileges.
