What it is

rustdesk-api through 2.7 contains an authorization bypass vulnerability that allows unauthenticated attackers to overwrite existing peer records by supplying only a target device ID to POST /api/sysinfo. Attackers can overwrite hostname, username, OS and uuid without uuid verification, then log in presenting that uuid to rebind the peer to their account.
