Meta, the Facebook and Instagram company, faces a Muse security warning

A newly disclosed security weakness that may not have a fix yet.

Software that can perform tasks instead of only giving answers.
permission（パーミッション）
The ability a user allows software to use.
What happened
Meta, the company behind Facebook and Instagram, built Muse, a personal AI agent. Ars Technica reported a serious zero-day affecting the assistant. Patrick Wardle, a macOS security researcher, found that other local apps or terminal commands might take control of Muse. The report says this could expose information that controls the Muse account and let an attacker use its broad permissions.
Muse can book appointments, fill forms, create documents, handle customer service, and make purchases. It can also connect with services such as email, calendars, and WhatsApp. This makes the issue more serious than a chatbot giving a wrong answer. A hijacked agent may be able to act for the user.
Background
An AI agent is software that can perform tasks, not only write replies. To perform those tasks, Muse needs access to accounts, files, and device features. More access creates more possible harm when a weakness is abused.
Meta’s own safety explanation describes several protections. Muse runs in a separate cloud environment for each user. The model should not see real account credentials. A separate permission system checks connections and network activity. Important actions can require approval from the user. Meta also opened a bug bounty program for security reports.
Those promises matter because the reported weakness appears to involve the app running on the user’s computer. The case shows that safety must cover the whole product. It cannot depend only on whether the model follows instructions correctly.
Why it matters
The main question is not whether Muse suddenly became malicious. The question is whether an outside program can turn a helpful assistant into a powerful control point. If one assistant connects email, calendars, files, cameras, and shopping, a single security problem may reach several parts of a person’s life.
This raises a design challenge for the whole AI industry. Agents need small, separate permissions. Sensitive actions need clear approval. Security checks should sit outside the model. These controls must also be tested by independent researchers.
What is confirmed
Wardle’s research demonstration reportedly showed ways to make Muse use powerful device abilities, including files and the camera. Ars Technica did not report confirmed mass theft or widespread attacks. It reported a security finding and proof-of-concept testing.
Amazon also began blocking Muse from shopping on its website. Amazon said third-party purchasing agents must respect a service’s decision about whether to participate. Meta did not answer Ars Technica’s emailed questions. Meta’s separate safety posts describe its intended protections, but they do not by themselves resolve the reported flaw.
What remains unknown
The public report does not establish which versions are affected. It does not say whether Meta has released a fix. It also does not show whether attackers used the weakness against real users. The size of the affected user group is unclear. So is the exact relationship between the local app and Meta’s cloud safeguards.
What to watch next
The next important signs are a clear response from Meta, a security update, and independent retesting. Users and businesses will also watch whether Amazon restores access. More broadly, AI agents will be judged by their permission limits and recovery plans, not only by their ability to complete tasks.

A report says another app might control Meta’s AI helper Muse. It does not confirm stolen data or a finished fix.

A serious security weakness found before its response is clear.

💡 The gist
- Meta, the company behind Facebook and Instagram, made Muse.
- Muse has a reported flaw that may let another app control it.
- The report does not confirm stolen data or a finished fix.
Muse is an AI helper that can take actions. It can organize appointments and fill out forms. It can create documents and help with shopping. It can connect to email, calendars, and messaging services.
Security researchers call a newly found serious weakness a zero-day. Patrick Wardle, a macOS security researcher, reported one in Muse. His tests suggested that a different program on the computer might control Muse without normal permission. That could let someone use powers Muse already has.
This matters because Muse is an AI agent. A chatbot mainly gives answers. An agent can change files or act inside other services. A mistake in a chatbot can be annoying. A stolen agent account could affect several parts of a person’s digital life.
Meta says Muse has several safety layers. It says each user gets a separate cloud space. It says the AI should not see real passwords or account keys. It also says a separate system checks important actions. Some actions require the user to approve them.
The report came from a researcher’s testing. It does not prove that criminals used the flaw. It does not prove that users lost information. The article also says Meta did not answer its questions.
Amazon stopped Muse from shopping on Amazon. The company said outside shopping agents must respect each website’s decision. This shows another problem for AI agents. They need permission from the services they use, not only from their users.
Several facts are still missing. We do not know every affected version. We do not know whether Meta fixed the flaw. We do not know whether attacks happened outside testing. The next signs will be Meta’s response, a patch, and independent tests.

Muse can help with calendars, messages, and shopping. A computer safety researcher found a weak spot. Another app might control Muse without permission. Then Muse might do things its owner did not ask for. The report does not say that someone stole data. Amazon stopped Muse from shopping on its website. Meta says Muse has safety checks. People will watch for a fix and more testing.
