A security researcher reports that Meta's Muse agent complied with a conversational request to archive accessible files and export them to Google Drive, producing 2.7GB compressed and 6.8GB unpacked. The archive appeared to include the assigned Linux environment's system files, internal documentation, integration code, memory, agent logs and SSH key files.

The researcher submitted the issue through Meta's bug-bounty program, which marked it "Not Applicable." He did not establish whether the keys were active, what access they enabled or whether files from infrastructure outside his assigned environment were exposed.
