Deserialization of Untrusted Data Affecting transformers package, versions [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.

NewCVE-2024-11394 (opens in a new tab)How to fix?
There is no fixed version for transformers.
Overview
transformers is a State-of-the-art Machine Learning for JAX, PyTorch and TensorFlow
Affected versions of this package are vulnerable to Deserialization of Untrusted Data through the handling of model files, due to the lack of proper validation of user-supplied data. This is only exploitable if the target visits a malicious page or opens a malicious Trax model file.
Note: The maintainers of this package are not addressing this vulnerability as it is limited to accessory conversion scripts and does not impact core library functions. The need for the attacker to provide a malicious model file which is then converted using the relevant script is considered an unrealistic attack vector. Since mitigation would require the complete removal of these scripts, the issue is not expected to be fixed.
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.
