Ray: Arbitrary code execution via ray.data.read_webdataset default decoder: pickle.loads(value) and torch.load(weights_only=False)

Summary ray.data.readwebdatasetpaths=... is a @PublicAPIstability="alpha" reader for WebDataset-format TAR files. Its default decoder=True invokes defaultdecoder on every sample's keys, which routes file extension to a decoder by extension. Two of those branches deserialize attacker-controlled...

CVE-2026-41486

Ray contains a remote code execution flaw (CVE-2026-41486) observed in Ray 2.49.0–2.54.0 where PyArrow reads Parquet extension types in metadata and Ray passes the bytes to cloudpickle.loads() during schema parsing, enabling arbitrary code execution before any row data is read. The issue affects ...
