Summary
OpenClaw allows unauthenticated discovery TXT records to steer routing and TLS pinning
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:
- 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.
Distribution / Exposure
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.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

- Clients now prefer the resolved service endpoint (SRV + A/AAAA) over TXT-provided routing hints.
- Discovery-provided fingerprints no longer override stored TLS pins.
- iOS/Android: first-time TLS pins require explicit user confirmation (fingerprint shown; no silent TOFU).
- iOS/Android: discovery-based direct connects are TLS-only.
- Android: hostname verification is no longer globally disabled (only bypassed when pinning).
Frequently Asked Questions
- What is CVE-2026-26327? CVE-2026-26327 is a high-severity security vulnerability in openclaw (npm), affecting versions < 2026.2.14. It is fixed in 2026.2.14.
- Which versions of openclaw are affected by CVE-2026-26327? openclaw (npm) versions < 2026.2.14 is affected.
- Is there a fix for CVE-2026-26327? Yes. CVE-2026-26327 is fixed in 2026.2.14. Upgrade to this version or later.
- Is CVE-2026-26327 exploitable, and should I be worried? Whether CVE-2026-26327 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2026-26327 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
