Deserialization of Untrusted Data

Overview flair is an A very simple framework for state-of-the-art NLP Affected versions of this package are vulnerable to Deserialization of Untrusted Data via the ClusteringModel.load function. An attacker can execute arbitrary code by providing a malicious model file that is loaded through this...

CVE-2026-76843

The official Flair wheels for 0.15.0 and 0.15.1 still contain flair/models/clustering.py, whose ClusteringModel.load static method returns pickle.loadsjoblib.loadstrmodelfile and so executes arbitrary Python while loading a model file. Loading a model supplied by an attacker therefore runs that...
