CVE-2025-5148

Local code execution via unsafe checkpoint deserialization

Published May 25, 2025 · Updated May 28, 2025

Unsafe deserialization in InspireMusic at commit bf32364bcb0d136497ca69f9db622e9216b029dd allows local users to execute arbitrary code. In inspiremusic/cli/model.py, InspireMusicModel.load passes LLM and flow checkpoint paths to torch.load without weights_only=True, enabling Pickle payload execution. The attacker must have local access and cause the application to load a crafted checkpoint; execution inherits the invoking process's privileges.
