Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

OpenClaw是openclaw开源的一个智能人工助理。 OpenClaw 2026.2.14之前版本存在数据伪造问题漏洞，该漏洞源于发现信标中的TXT记录未经身份验证，某些客户端将TXT值视为权威的路由/固定输入，在共享/不受信任的LAN上，攻击者可发布恶意服务，可能导致客户端连接到攻击者控制的端点或接受攻击者证书，从而泄露网关凭据。

Vulnerability Title
OpenClaw allows unauthenticated discovery TXT records to steer routing and TLS pinning
Source: CVE Program / CVE List V5
Vulnerability Description
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).
