CVE-2025-69443
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedRemote Code Execution in coleam00 Archon 0.1.0. A crafted HTML page, when accessed by a victim, can execute commands, run prompts on behalf of the user, control the Archon UI features, and steal all Archon information available on the UI including API keys.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is a Remote Code Execution vulnerability in coleam00 Archon 0.1.0. A crafted HTML page, when accessed by a victim, can execute arbitrary commands, run prompts on behalf of the user, control UI features, and exfiltrate sensitive information including API keys from the Archon interface. The attack likely exploits improper sanitization of HTML content leading to code execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed Archon versionCheck the version of coleam00 Archon currently deployed in your environment. This may be visible in the application UI, in package.json, in the software documentation, or via an API endpoint that returns version information.Affected if The installed version is 0.1.0, as this is the only affected version listed in the CVE.
-
Locate HTML rendering functionalityInspect the codebase or application for code that renders or processes HTML content. Look for functions that accept HTML input and display it in the UI, particularly any endpoints or interfaces that accept external HTML for display.Affected if The application renders HTML content (especially from untrusted or external sources) without server-side sanitization, which would enable the XSS-to-RCE attack chain described.
-
Verify API key exposure to client-side JavaScriptExamine the application's frontend JavaScript code and network responses to determine if API keys, credentials, or sensitive configuration data are accessible to client-side scripts or transmitted to the browser.Affected if API keys or other sensitive credentials are exposed to client-side JavaScript or the browser console, allowing exfiltration via malicious HTML.
-
Check for Content Security Policy headersInspect HTTP responses from the Archon application using browser developer tools or a command-line HTTP client (curl, wget). Look for the Content-Security-Policy header in response headers.Affected if The application lacks a restrictive Content Security Policy header, or CSP headers are missing entirely, allowing script execution from malicious HTML content.
-
Review user input handling for HTML contentAudit how the application handles user-provided content that could be rendered in the interface. Test whether HTML tags, script elements, or event handlers are stripped, escaped, or passed through when submitted as input.Affected if User-supplied HTML content is rendered in the UI without proper sanitization or encoding, enabling code execution when a victim views a crafted page.
If running Archon 0.1.0 and the application renders untrusted HTML content without sanitization while exposing API keys to client-side scripts, the environment is affected by this RCE vulnerability.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement rigorous input validation and sanitization for all HTML content, enforce Content Security Policy (CSP) headers to restrict script execution, and ensure proper output encoding when rendering user-supplied content in the UI. API keys should not be exposed to client-side JavaScript.
