Technical summary

OpenClaw for iOS versions >= 2026.7.1 and < 2026.8.11 do not enforce saved Gateway TLS pins in the Control UI. While native connections enforced the saved Gateway fingerprint, the authenticated Terminal and session Dashboard WebViews omitted it. If a user had accepted a Gateway fingerprint, an attacker able to redirect the same host and port and present a different certificate that is accepted by iOS system trust can serve a replacement Control UI page; opening the Terminal or a session Dashboard then allows that page to read the injected Gateway token or password. The stolen credential can grant operator access, including reading sensitive Gateway state and invoking host-capable tools. This issue is fixed in 2026.8.11.
