CVE-2025-50472
Apache Spark - Deserialization Code Execution Vulnerability
Description

The modelscope/ms-swift library thru 2.6.1 is vulnerable to arbitrary code execution through deserialization of untrusted data within the `load_model_meta()` function of the `ModelFileSystemCache()` class. Attackers can execute arbitrary code and commands by crafting a malicious serialized `.mdl` payload, exploiting the use of `pickle.load()` on data from potentially untrusted sources. This vulnerability allows for remote code execution (RCE) by deceiving victims into loading a seemingly harmless checkpoint during a normal training process, thereby enabling attackers to execute arbitrary code on the targeted machine. Note that the payload file is a hidden file, making it difficult for the victim to detect tampering. More importantly, during the model training process, after the `.mdl` file is loaded and executes arbitrary code, the normal training process remains unaffected'meaning the user remains unaware of the arbitrary code execution.

Solution
Update the library and sanitize inputs to prevent arbitrary code execution via deserialization.
  • Update modelscope/ms-swift library to version 2.6.2 or later.
  • Avoid loading untrusted or unknown model metadata files.
  • Sanitize all input data before deserialization.
