## Summary

InternScience InternAgent, an AI research agent framework, is affected by a flaw in its LoRA model loading component, where a user-supplied base model path can cause the software to load and run code from an untrusted source. An attacker could potentially exploit this remotely, which may allow them to run unauthorized code or compromise the system.

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

## Affected

- InternScience InternAgent: 1.5.0

## Description

A weakness has been identified in InternScience InternAgent 1.5.0. This affects the function train of the file tasks/AutoChem/code/experiment.py of the component LoRA Loading. This manipulation of the argument base_model_name_or_path causes inclusion of functionality from untrusted control sphere. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks.
