CVE-2025-50460Public exploitNetwork attack vector

Code execution via unsafe YAML deserialization

Published Aug 1, 2025 · Updated Aug 1, 2025

Unsafe deserialization in ModelScope ms-swift 3.6.3 and earlier allows attackers to execute code through a crafted YAML run configuration. tests/run.py passes the file selected by --run_config to yaml.load with FullLoader, permitting Python object construction during parsing. Exploitation requires control of that configuration file and execution of the test runner, granting code execution with the runner's privileges.
