Summary
The Gateway tool accepted a tool-supplied gatewayUrl without sufficient restrictions, which could cause the OpenClaw host to attempt outbound WebSocket connections to user-specified targets.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected versions:
<= 2026.2.13 - Patched versions:
>= 2026.2.14(planned)
What Is Needed To Trigger This
This requires the ability to invoke tools that accept gatewayUrl overrides (directly or indirectly). In typical setups this is limited to authenticated operators, trusted automation, or environments where tool calls are exposed to non-operators.
In other words, this is not a drive-by issue for arbitrary internet users unless a deployment explicitly allows untrusted users to trigger these tool calls.
Details
Some tool call paths allowed gatewayUrl overrides to flow into the Gateway WebSocket client without validation or allowlisting. This meant the host could be instructed to attempt connections to non-gateway endpoints (for example, localhost services, private network addresses, or cloud metadata IPs).
Impact
In the common case, this results in an outbound connection attempt from the OpenClaw host (and corresponding errors/timeouts). In environments where the tool caller can observe the results, this can also be used for limited network reachability probing. If the target speaks WebSocket and is reachable, further interaction may be possible.
Fix
Tool-supplied gatewayUrl overrides are now restricted to loopback (on the configured gateway port) or the configured gateway.remote.url. Disallowed protocols, credentials, query/hash, and non-root paths are rejected.

Thanks @p80n-sec 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 needs basic access or low-level privileges. 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 low impact on the integrity of the data. There is a low impact on the availability of the system.
Exploitation activity has been observed. Apply available patches or mitigations urgently.
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.
