PT-2026-53444

Horovod versions up to and including v0.28.1 are vulnerable to unauthenticated remote code execution. The vulnerability is due to improper handling of base64-encoded data in the ElasticRendezvousHandler, a subclass of KVStoreHandler. Specifically, the put value method in ElasticRendezvousHandler...

CVE-2026-41486

Ray is an AI compute engine. From version 2.54.0 to before version 2.55.0, Ray Data registers custom Arrow extension types ray.data.arrowtensor, ray.data.arrowtensorv2, ray.data.arrowvariableshapedtensor globally in PyArrow. When PyArrow reads a Parquet file containing one of these extension type...

CVE-2026-4137

A flaw was found in mlflow/mlflow. Insecure permissions on temporary directories allow local attackers to tamper with model artifacts, such as cloudpickle-serialized Python objects. This manipulation can lead to arbitrary code execution when the tampered artifacts are deserialized. This...
