Alert meAnalysisAIv1 – Mar 12, 2026
OpenClaw's mDNS/Bonjour discovery beacons transmit unauthenticated TXT records that iOS, macOS, and Android clients treat as authoritative for routing and TLS certificate pinning, allowing an attacker on a shared LAN to advertise a rogue service and redirect connections to attacker-controlled endpoints. An attacker can exploit this to bypass TLS pinning validation and potentially capture Gateway credentials through man-in-the-middle attacks. The vulnerability affects OpenClaw versions prior to 2026.2.14 and requires network proximity but no user interaction.
Earlier versions of this analysis (1)
Openclaw versions up to 2026.2.14 is affected by insufficient verification of data authenticity (CVSS 6.5).

This vulnerability (CWE-345: Insufficient Verification of Data Authenticity) affects Openclaw. OpenClaw is a personal AI assistant. Discovery beacons (Bonjour/mDNS and DNS-SD) include TXT records such as lanHost, tailnetDns, gatewayPort, and gatewayTlsSha256. TXT records are unauthenticated. Prior to version 2026.2.14, some clients treated TXT values as authoritative routing/pinning inputs. iOS and macOS used TXT-provided host hints (lanHost/tailnetDns) and ports (gatewayPort) to build the connection URL. iOS and Android allowed the discovery-provided TLS fingerprint (`gatew

OpenClaw is a personal AI assistant. Discovery beacons (Bonjour/mDNS and DNS-SD) include TXT records such as lanHost, tailnetDns, gatewayPort, and gatewayTlsSha256. TXT records are unauthenticated. Prior to version 2026.2.14, some clients treated TXT values as authoritative routing/pinning inputs. iOS and macOS used TXT-provided host hints (lanHost/tailnetDns) and ports (gatewayPort) to build the connection URL. iOS and Android allowed the discovery-provided TLS fingerprint (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. As of time of publication, the iOS and Android apps are 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. Version 2026.2.14 fixes the issue. Clients now prefer the resolved service endpoint (SRV + A/AAAA) over TXT-provided routing hints. Discovery-provided fingerprints no longer override stored TLS pins. In iOS/Android, first-time TLS pins require explicit user confirmation (fingerprint shown; no silent TOFU) and discovery-based direct connects are TLS-only. In Android, hostname verification is no longer globally disabled (only bypassed when pinning).
Executive ViewAI
Organizations using OpenClaw should be aware of notable risk from CVE-2026-26327 rated CVSS 6.5. Exploitation could compromise the security of affected deployments. A patch is available and should be applied during regular vulnerability management.
Apply vendor patch. If patching is delayed: restrict network access and enable monitoring.
