# Meta patches a flaw that put Muse virtual machines at risk

2026-09-25. Found through Meta's bug bounty program, the bug could have given an attacker a way into the cloud machine holding a Muse user's emails and files.

Meta has closed a security hole, flagged via its bug bounty program, that could have exposed the virtual machine each Muse user is assigned. Meta rated it SEV-2, the second-highest level on its scale.

That machine keeps copies of the emails and files a user connects. Alongside the fix, Meta made the safety warnings in the app clearer.

The incident is a reminder that everything you connect to Muse is copied to that machine, so every linked account widens what a single flaw can expose.

## Why it matters to you

Keep the Muse app updated and pay attention to its safety warnings. Link an account only when a current task depends on it.
