CVSS 7.7 · HIGH

CVE-2026-43573

OpenClaw before 2026.4.10 contains a server-side request forgery policy bypass vulnerability in existing-session browser interaction routes. Attackers can bypass SSRF navigation guards to interact with or navigate to unauthorized targets without policy enforcement.

Analysis

OpenClaw appears to be a specialized tool for browser interaction or game engine re-implementation with limited deployment. While SSRF is a high-severity issue, the product is not a standard part of the common dev stack, and the exploit requires an existing session.
