Summary

peft Unsafe Deserialization via torch.load() Without weights_only in LoRA-GA and CorDA Modules

Details

Hugging Face peft's LoRA-GA and CorDA initialization modules (src/peft/tuners/lora/corda.py lines ~102 and ~163, and src/peft/tuners/lora/loraga.py line ~101) call torch.load() on config-specified cache/covariance files without weightsonly=True, bypassing peft's own safe-loading wrapper used elsewhere in the codebase. Because torch.load() without weightsonly=True performs full pickle deserialization, loading a malicious cache or covariance file (e.g. a shared/downloaded LoRA-GA or CorDA cache) results in arbitrary code execution.
