Meta patches multiple security vulnerabilities in the Muse agent

We have since patched and paid bounties for several findings: • A webpage mimicked Muse's own browser tool to trick agents into performing actions that should have been blocked • Certain email formats bypassed our one-time password desensitization • A malicious Android app could steal credentials via unverified links • The automatic updater for Mac applications could be abused by attackers with access to the machine to escalate privileges
