Attack-Flow Graph

Executive Summary

CVE-2026-43573 is a server-side request forgery (SSRF) policy bypass vulnerability found in OpenClaw versions before 2026.4.10. It specifically affects existing-session browser interaction routes, where attackers can bypass SSRF navigation guards. This allows them to interact with or navigate to unauthorized targets without the usual policy enforcement that prevents such actions.

The vulnerability arises because certain navigation or interaction routes during an active session do not apply the SSRF navigation guard, enabling unauthorized access or navigation. The fix involves implementing a three-phase navigation guard and SSRF post-checks to ensure navigation policies are strictly enforced, even when delayed JavaScript redirects occur.

Impact Analysis

This vulnerability can allow attackers to bypass security controls designed to prevent unauthorized server-side requests. By exploiting this SSRF policy bypass, attackers could interact with internal or restricted targets that should normally be inaccessible, potentially leading to unauthorized data access or manipulation.

Because the SSRF navigation guards are bypassed in existing-session browser interactions, attackers might perform actions or navigate to targets without proper authorization checks, increasing the risk of unauthorized access within the affected system.

Mitigation Strategies

To mitigate the CVE-2026-43573 vulnerability, you should upgrade OpenClaw to version 2026.4.10 or newer, as this version includes the security fix that enforces SSRF navigation guards on existing-session browser interaction routes.

The fix involves implementing a three-phase navigation guard and SSRF post-checks to ensure navigation policies cannot be bypassed by delayed JavaScript redirects or other interaction routes.

Using the latest stable release, such as [email protected], is recommended to ensure all patches and security measures are applied.
