Description

agent-device from 0.21.36 before 0.21.37 contains a local file disclosure vulnerability that allows authenticated remote callers to read daemon-host files by opening file:// URLs. Attackers can send an open command with a file:// target through /rpc, then issue snapshot to read any plaintext file readable by the daemon account.
