Summary
The gateway WebSocket connect handshake could allow skipping device identity checks when auth.token was present but not yet validated.
Details
In src/gateway/server/ws-connection/message-handler.ts, the device-identity requirement could be bypassed based on the presence of a non-empty connectParams.auth.token rather than a validated shared-secret authentication result.
Impact
In deployments where the gateway WebSocket is reachable and connections can be authorized via Tailscale without validating the shared secret, a client could connect without providing device identity/pairing. Depending on version and configuration, this could result in operator access.
Deployment Guidance
Per OpenClaw security guidance, the gateway should only be reachable from a trusted network and by trusted users (for example, restrict Tailnet users/ACLs when using Tailscale Serve).
If the gateway WebSocket is only reachable by trusted users, there is typically no untrusted party with network access to exploit this issue.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected:
<= 2026.2.1 - Fixed:
>= 2026.2.2
Fix
Device-identity skipping now requires validated shared-secret authentication (token/password). Tailscale-authenticated connections without validated shared secret require device identity.

Thanks @simecek for reporting.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Active exploitation in the wild has been confirmed. Immediate patching or mitigation is required.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
