## Affected

- yoshitomo-matsubara torchdistill: 1.1.0, 1.1.1, 1.1.2, 1.1.3, 1.1.4, 1.1.5

## Description

A flaw has been found in yoshitomo-matsubara torchdistill up to 1.1.5. This affects the function load_ckpt of the file torchdistill/common/main_util.py. Executing a manipulation of the argument src_ckpt can lead to deserialization. The attack needs to be launched locally. The exploit has been published and may be used. The project maintainer explains: "This is very similar to an internal report that GH auto-generated for the owner before, which I found tolerable for this project at that time. So I will close this as duplicate."
