## Summary

NPC-Worldwide's npcpy library contains a code injection flaw in its load_sft_model function, which takes a base_model_name_or_path argument that an attacker can manipulate to run arbitrary code. The attack can be launched remotely without logging in but requires a user to take some action, and it is not known to be used in attacks.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.
