openclaw is a 🦞 OpenClaw — Personal AI Assistant
Affected versions of this package are vulnerable to User Impersonation during authentication. An attacker can gain unauthorized access to HTTP gateway routes by exploiting the improper application of tokenless Tailscale authentication headers, bypassing token or password requirements in trusted-network deployments.
Note: This is only exploitable if tokenless Tailscale authentication is enabled and the deployment relies on token/password authentication for HTTP gateway routes.
Workaround
This vulnerability can be mitigated by keeping the Gateway loopback-only or otherwise within a trusted host/network boundary, using Tailscale serve/funnel for remote access, and restricting tokenless Tailscale authentication to Control UI websocket login.
