CVE-2026-111324 Details
Description
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.
An authorization bypass vulnerability has been identified in the Rustdesk API server, specifically in versions through 2.7. This vulnerability allows unauthenticated attackers to overwrite existing peer records by sending a POST request to the /api/sysinfo endpoint with only the target device ID. The attackers can modify several fields, including hostname, username, operating system, and UUID, without any verification of the UUID. This exploitation enables attackers to log in with the presented UUID and rebind the peer record to their account.
Move the /api/sysinfo route registration below the authentication middleware to require a valid token for access. Additionally, implement checks to ensure that only the authenticated owner of a peer can modify its information.
