Deserialization of Untrusted Data Affecting kedro-datasets package, versions [5.0.0,9.5.0)
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

CVE-2026-62997 (opens in a new tab)How to fix?
Upgrade kedro-datasets to version 9.5.0 or higher.
Overview
kedro-datasets is a Kedro-Datasets is where you can find all of Kedro's data connectors.
Affected versions of this package are vulnerable to Deserialization of Untrusted Data in the PyTorchDataset process. An attacker can execute arbitrary code by supplying a malicious .pt model file from an attacker-controlled source, which is then loaded without proper safety checks. This is only exploitable if the opt-in experimental component is used and untrusted files are loaded with PyTorch versions earlier than 2.6.
Details
Serialization is a process of converting an object into a sequence of bytes which can be persisted to a disk or database or can be sent through streams. The reverse process of creating object from sequence of bytes is called deserialization. Serialization is commonly used for communication (sharing objects between multiple hosts) and persistence (store the object state in a file or a database). It is an integral part of popular protocols like Remote Method Invocation (RMI), Java Management Extension (JMX), Java Messaging System (JMS), Action Message Format (AMF), Java Server Faces (JSF) ViewState, etc.
Deserialization of untrusted data (CWE-502) is when the application deserializes untrusted data without sufficiently verifying that the resulting data will be valid, thus allowing the attacker to control the state or the flow of the execution.
