Discovery beacons (Bonjour/mDNS and DNS-SD) include TXT records such as lanHost, tailnetDns, gatewayPort, and gatewayTlsSha256. TXT records are unauthenticated.
Prior to the fix, some clients treated TXT values as authoritative routing/pinning inputs:
lanHost/tailnetDns) and ports (gatewayPort) to build the connection URL.gatewayTlsSha256) to override a previously stored TLS pin.On a shared/untrusted LAN, an attacker could advertise a rogue _openclaw-gw._tcp service. This could cause a client to connect to an attacker-controlled endpoint and/or accept an attacker certificate, potentially exfiltrating Gateway credentials (auth.token / auth.password) during connection.
The iOS and Android apps are currently alpha/not broadly shipped (no public App Store / Play Store release). Practical impact is primarily limited to developers/testers running those builds, plus any other shipped clients relying on discovery on a shared/untrusted LAN.
CVSS can still be used for the technical (base) severity of the bug; limited distribution primarily affects environmental risk.
