Joseph Cox cited a 404 Media report saying Meta scrambled to fix serious Muse vulnerabilities before launch, including a VM escape that could have exposed internal databases. A separate summary post said Muse runs agents in per-user VMs.

Joseph Cox cited a 404 Media report saying Meta rushed to fix serious Muse vulnerabilities just before launch, including a VM escape that could have exposed internal databases and was escalated to Mark Zuckerberg. A separate summary post also said Muse runs agents in per-user VMs, but that architecture detail is not independently inspected here.

Joseph Cox cited a 404 Media report saying Meta scrambled to fix serious Muse vulnerabilities in the immediate lead-up to launch, including "a VM escape that could have let a hacker break out of Muse and into Meta's own sensitive databases." Cox also wrote that the issue "was escalated to Zuckerberg" (Cox's post).

Featured Source

A separate summary post described the same reported issue by saying, "404 Media reports Meta rushed to fix Muse VM escapes before launch; one could have exposed internal databases" (summary post). Because the inspected record here is limited to social posts summarizing 404 Media, the clearest supported framing is a reported VM escape vulnerability before launch, not independently confirmed details beyond that.

That same summary post also said, "Muse runs agents in per-user VMs" (summary post). In the supplied evidence, that architecture detail appears in the summary post and is not independently inspected here.

On the available record, the reportable development is narrow but clear: a post from Cox points to 404 Media reporting that Meta hurried to fix a serious Muse security issue before launch, including a VM escape that could have exposed internal databases, while a separate post adds an unverified architecture detail about per-user virtual machines.
