The presence of this vulnerability remains uncertain at this time. The project maintainer explains: "On paper you're correct, this is a vulnerability. In practice, nothing your AI generated shows how it makes users vulnerable. It's open source. Someone can mod the shell allow list or remove that system. Present an actual poc that shows a threat to users."
