Show the technical text from the sources

A weakness has been identified in Ultralytics FastSAM up to b4ed20c2fed75eadc5aa7d8b09fedd137b873b52. This affects the function session.get_modelmeta.custom_metadata_map of the file ultralytics/nn/autobackend.py of the component AutoBackend Model Loading. This manipulation of the argument imgsz/names/kpt_shape causes improper neutralization of directives in dynamically evaluated code. The attack requires local access. This product uses a rolling release model to deliver continuous updates. As a result, specific version information for affected or updated releases is not available. The project was informed of the problem early through an issue report but has not responded yet.
