Mac users could still be tricked: prompting attacks vs. the requirement that code runs locally
GitHub ● Covered by 2 sources
A proof-of-concept shows a local attacker can hijack Muse’s dictation traffic on macOS. That could turn Muse’s permissions into a handy boost for malware already running on the machine.

A security researcher has put out proof-of-concept code for a local Muse vulnerability that can redirect the app’s dictation traffic. The wrinkle is ugly: Muse appears to trust an undocumented setting called endo_voyager_dictation_endpoint, and a local process can change it without special privileges.
Once that endpoint is rewritten, dictated prompts no longer have to go where the user expects. They can be sent to an attacker-controlled server instead, opening the door to captured audio and prompts, prompt injection, theft of Muse authentication material, and abuse of whatever access the user has already granted the app.
That last part is the real story. This is not a remote break-in. The attacker still needs code running locally as the user. But Muse may have more reach than ordinary malware, which makes it a convenient place to steal from and then expand from.
The proof-of-concept also highlights how much surface area Muse exposes. The author says the PoC only covers a subset of the more than 50 commands Muse offers, but it is enough to show the basic trick: click the microphone button, dictate something, and the traffic can be pushed somewhere else.
So the risk here is less “someone hacks your Mac from the internet” and more “something already on your Mac gets a better seat at the table.” On a machine where software is often trusted by default, that kind of access amplification is exactly the sort of mess attackers enjoy.
My take — AI-written commentary, not fact-checked reporting
This is the kind of bug that makes local malware boringly practical. The industry keeps treating local code execution like the finish line, when in reality it’s often the starting gun for privilege theft with nicer branding. If an app can quietly carry a user’s trust around like a tote bag, someone will eventually reach in and take the good stuff.
