Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
MONAI versions before 1.6.0 are vulnerable to arbitrary code execution through the NumpyReader class, which loads .npy and .npz files with pickle deserialization always enabled and not overridable by users. An attacker who can supply a crafted .npy or .npz file that a user loads through MONAI's standard pipeline, such as LoadImage or the dataset classes, could run code on the machine processing it. Upgrade to MONAI 1.6.0 or later, which contains the fix.
