Meta's new Muse AI app hit with a 0-day vulnerability shortly after security boasts
Just weeks after Meta boasted about the bulletproof security of its new Muse AI agent, a security researcher found a 0-day vulnerability in the Mac app.

For the past two weeks, Meta has been promoting the security features of its new Muse personal AI agent to anyone willing to listen. The company heavily marketed its dedicated Secure VM, a monitoring system called Sentinel, and bug bounty rewards of up to $300,000. Mark Zuckerberg himself publicly vouched for the agent, stating it was built from the ground up with privacy and security in mind.
However, those boasts took a hit when macOS security researcher Patrick Wardle discovered a 0-day vulnerability in the Muse Mac app. Wardle humorously dubbed the finding "not-a-mused," reflecting on what must have been a stressful 24 hours for the engineering teams at Meta.
The swift discovery of a critical flaw right after public assertions of top-tier security highlights the ongoing challenges tech giants face when deploying complex AI agents. While automated platforms and hardware-level isolation are powerful tools, human error and oversight can still slip through the cracks before widespread adoption.
This incident serves as an important reminder for the global tech community, including developers and enterprise users, about the inherent risks of rushing new AI technologies to market. No matter how robust a system appears on paper or how high the bug bounty rewards are, vulnerabilities remain an inevitable hurdle in modern software development.
As the security community awaits an official fix from Meta, the discovery underscores the vital role independent researchers play in keeping tech giants accountable. Users interacting with advanced personal AI agents are advised to stay vigilant and apply security updates as soon as they become available.
