OpenSave before 2.4.0-beta.1 Authentication Bypass via Spoofed Relay Sender

Type: advisorySource: Official CVE List1 source record

OpenSave before 2.4.0-beta.1 fails to validate sender identity in WAN relay requests, allowing unpaired room members to impersonate paired devices by spoofing the RelayMessage From field. Attackers who know the room code can join, read paired peer identifiers from announcements, and send forged requests to access protected sync routes including save data, snapshots, and file operations.
