Ars Technica has disclosed a serious 0-day vulnerability in Muse, Meta's AI assistant. The flaw is notable because Muse is described as having extraordinary privileges, meaning it can interact with a user's system at a level far beyond typical assistants. This makes any successful exploit particularly dangerous.
The reported attack vector is a ClickFix-style social engineering scheme, where a user is tricked into pasting a malicious command or clicking a crafted prompt. According to the source, this simple interaction is enough to completely hijack the agent, giving the attacker the same broad access that Muse itself holds.
Because the source is a single report, there is no independent confirmation or contrasting analysis to weigh. The key takeaway is that a highly privileged AI assistant can become a powerful attack surface if its safeguards fail, and the ease of the ClickFix method raises immediate concerns for users.
