CVE-2026-66418

OpenClaw Dashboard v3.0.0 Stored XSS via Failed Login Username Field

Published Jul 30, 2026 CVSS 4.0 · 9.3 Critical EPSS < 1% KEV · Not listed
Description
OpenClaw Dashboard v3.0.0 contains a stored cross-site scripting vulnerability that allows unauthenticated remote attackers to inject arbitrary HTML and script payloads by submitting a crafted username in a failed login POST request, which is recorded verbatim in the audit log. When an administrator opens the notification panel, the unescaped log entry is rendered via innerHTML with a permissive Content-Security-Policy allowing inline event handlers, enabling the attacker-supplied payload to execute in the administrator's session and interact with authenticated endpoints including agent instruction file editing and configuration changes.
