Patrick Wardle, founder of Objective-See, disclosed a zero-day vulnerability in Meta's Muse for macOS. The flaw involves an undocumented configuration setting, endo_voyager_dictation_endpoint, which can be modified by an unprivileged local process to redirect dictation traffic to an attacker-controlled server. This enables the interception of prompts, injection of malicious instructions, and theft of authentication material. Wardle released a proof-of-concept exploit named 'not-a-mused.' The vulnerability requires prior local code execution but amplifies the impact of low-privilege malware by leveraging Muse's extensive delegated permissions across connected services.
Security researcher Patrick Wardle disclosed a zero-day vulnerability in Meta's Muse for macOS. The flaw allows malware already running under a user account to hijack the assistant by modifying an undocumented configuration setting called endo_voyager_dictation_endpoint. This modification redirects Muse's dictation traffic from its intended destination to an attacker-controlled server.
Once the endpoint is redirected, an attacker can capture dictated audio and prompts before they reach Muse's backend. This allows the manipulation of instructions delivered to the agent and the theft of authentication data associated with the victim's account. Wardle released a proof-of-concept exploit named 'not-a-mused' to demonstrate this capability.
The vulnerability does not provide remote code execution against a clean Mac; an attacker must first gain the ability to run code as the local user. However, Wardle argues that the defect acts as access amplification, allowing ordinary malware constrained by macOS privacy controls to exploit the broader authority already granted to the agent.
Meta states that Muse can work with files, applications, and browser tabs, connect to email and calendars, browse the web, make purchases, and continue performing tasks in the background. Wardle's proof of concept implements a subset of more than 50 commands exposed by Muse, with separate demonstrations showing the compromised account identifying linked devices and directing an online iPhone to return location information or initiate a Bluetooth Low Energy scan.

This disclosure highlights the security risks associated with highly privileged AI agents that hold broad access to user data, files, and connected services. When a trusted agent is compromised, it can act as a single point of failure, allowing attackers to bypass standard macOS privacy controls and access sensitive information across multiple devices. The incident underscores the need for robust security measures in design, particularly regarding permission management and the isolation of agent processes from local system vulnerabilities. It also raises concerns about the difficulty of detecting malicious actions when they are executed through a trusted, signed application.
The vulnerability highlights how a low-privilege foothold can become dangerous when a trusted agent holds expansive delegated authority across connected services. A compromised agent could inherit the extensive permissions and connected-service access that users have entrusted to Muse, creating a pathway for and session hijacking.
Endpoint detection tools may struggle to distinguish actions initiated by a user, the agent, or an attacker when commands are executed through a trusted, signed application. This makes it difficult for security systems to detect and respond to malicious activities carried out through the compromised agent.
The disclosure intensifies concerns about highly privileged AI agents becoming single points of failure. If an attacker controls the trusted command channel, they may be positioned to misuse connected resources, potentially extending the impact beyond the infected Mac to other linked devices and services.
Meta markets Muse as a security-focused personal agent built around a dedicated Secure VM, protected credential storage, and user-controlled permissions. However, this vulnerability suggests that these security measures may not be sufficient to prevent exploitation if the agent's configuration can be manipulated by local malware.

Monitor for a security patch from Meta addressing the endo_voyager_dictation_endpoint vulnerability. Watch for further details on the scope of the exploit, including whether it affects other platforms or versions of Muse. Observe how Meta responds to the disclosure, including any updates to their bug bounty program or security guidelines for users. Additionally, track industry reactions and potential regulatory scrutiny regarding the security standards for AI agents with high-level system access.
Monitor for a security patch from Meta addressing the endo_voyager_dictation_endpoint vulnerability. Until a verified fix is available, Mac users should treat Muse as a high-value security target and consider pausing the application or revoking unnecessary permissions.
Watch for further details on the scope of the exploit, including whether it affects other platforms or versions of Muse. Wardle's proof of concept currently focuses on macOS, but the underlying vulnerability may have broader implications for other operating systems or agent implementations.
Observe how Meta responds to the disclosure, including any updates to their bug bounty program or security guidelines for users. Meta operates a public bug bounty offering rewards of up to $300,000 for qualifying Muse security flaws or impactful -injection reports, but had not publicly responded to Wardle's specific findings when initial reports appeared.
Track industry reactions and potential regulatory scrutiny regarding the security standards for AI agents with high-level system access. The incident may discussions about best practices for securing AI agents and protecting user data in the face of emerging threats.
