OpenClaw iOS Control UI Gateway TLS Pin Bypass

Publication date: 2026-09-26

Last updated on: 2026-09-26

Assigner: VulnCheck

Description
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.

Executive Summary

CVE-2026-100551 is a TLS pin enforcement bypass in OpenClaw for iOS versions between 2026.7.1 and 2026.8.10. The Control UI fails to enforce saved Gateway TLS pins, unlike native connections. Attackers can redirect traffic to a malicious host with a valid iOS-trusted certificate and inject a fake Control UI page. When users access Terminal or Dashboard via WebViews, the injected page can steal Gateway tokens or passwords, granting operator-level access.

Detection Guidance

Detecting this vulnerability requires checking the OpenClaw iOS app version. If your version is between 2026.7.1 and 2026.8.10, the app is vulnerable. Use the App Store or device settings to verify the installed version.

Impact Analysis

An attacker could steal Gateway tokens or passwords, allowing them to gain operator access. This includes reading sensitive Gateway state and using host-capable tools. The impact is high as it compromises confidentiality, integrity, and availability of the system.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating compliance requirements for data protection such as GDPR and HIPAA. Unauthorized access risks data breaches, which may result in legal penalties and reputational damage.

Mitigation Strategies

Immediately update OpenClaw for iOS to version 2026.8.11 or later. Avoid using Terminal or Dashboard for pinned Gateways if network routing or certificate authorities are untrusted until the update is applied.
