CVE-2025-50472
The modelscope/ms-swift library thru 2.6.1 is vulnerable to arbitrary code execution through...
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.
