CVE-2026-66421
OpenClaw Dashboard contains a stored cross-site scripting vulnerability that allows unauthenticated remote attackers to execute arbitrary JavaScript in the administrator's browser session by injecting HTML markup into agent transcript messages processed through the sessions API. Attackers can craft a message containing inline event handler payloads such as an img tag with an onerror attribute within the 60-character rendering budget, which is stored in the session transcript and interpolated unsanitized into innerHTML on the default landing page, allowing theft of session tokens and unauthorized calls to authenticated administrative endpoints including agent instruction file modification.

CVE-2026-68503
LazyOwn RedTeam/APT Framework is an AI-powered C2 and red-team operations framework. Prior to 0.2.154, LazyOwn ships default C2 credentials LazyOwn and LazyOwn in payload.json and core/payload_schema.py and passes them unchanged to lazyc2.py HTTP Basic authentication, allowing any network-reachable attacker who knows the defaults to authenticate to the C2 dashboard with operator-level access. This issue is fixed in 0.2.154.

CVE-2026-68502
LazyOwn RedTeam/APT Framework is an AI-powered C2 and red-team operations framework. Prior to 0.2.154, LazyOwn's lazyc2.py registers an unauthenticated Socket.IO input event handler that dispatches data.get('value') to LazyOwnShell.one_cmd, reaching LazyOwnShell.do_cmd and subprocess.call(command, shell=True), allowing unauthenticated remote code execution in the C2 process. This issue is fixed in 0.2.154.

CVE-2026-66418
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.

CVE-2026-67594
Spikster through commit e1cdf8c contains a missing authentication vulnerability that allows unauthenticated remote attackers to access all API routes by exploiting the unattached CipiAuth middleware, which is registered but never applied to any route in the API routing configuration. Attackers can invoke approximately 50 unprotected API endpoints to enumerate and provision servers, reset root passwords, read and write arbitrary files on the host, and create database users.
