2026-09-27 · 1 source · Economic Times ETtech

In short

Meta tightened a safety warning for Muse after an outside researcher found a security flaw and reported it through the company’s bug bounty program. The issue was not previously disclosed and may have let someone reach a user’s dedicated virtual machine, which can hold emails and files.

This matters because it could expose private data stored in the cloud. The reporting does not say whether any accounts were actually broken into.
