Meta Patches Muse AI Following Zero-Day Vulnerability Discovery

The flaw stemmed from design choices that prioritized cloud-based processing over on-device execution, combined with an open architecture that allowed any local application to modify Muse's internal configurations. Wardle demonstrated that an attacker could leverage these privileges to capture photos or write malicious files to disk without triggering user alerts. He noted that the assistant effectively served as a shortcut for complex malware, bypassing the need for traditional data-stealing techniques.

Meta released a patch shortly after the security findings were publicized. While the company acknowledged the gap, it characterized the issue as a local privilege escalation rather than a remote threat, arguing that the practical risk to users remained limited. This incident highlights a growing tension between the rapid deployment of AI-integrated tools and the foundational security standards required to protect sensitive user environments.
