OpenClaw versions prior to 2026.2.14 contain a server-side request forgery vulnerability in the optional Tlon Urbit extension that accepts user-provided base URLs for authentication without proper validation. Attackers who can influence the configured Urbit URL can induce the gateway to make HTTP requests to arbitrary hosts including internal addresses.
Weakness
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
