# Security Policy

## Reporting a Vulnerability

If you discover a security vulnerability in Claude Workspace, please report it responsibly.

**Do NOT open a public GitHub issue for security vulnerabilities.**

Instead, report via [GitHub Security Advisories](https://github.com/outsourc-e/claude-workspace/security/advisories) or DM [@ericousodev on X](https://x.com/ericousodev).

We will acknowledge your report within 48 hours and aim to provide a fix within 7 days for critical issues.

## Scope

- Claude Workspace web application code
- API routes and Claude communication
- Authentication and session management
- Client-side data handling and rendering
- Exec approval and human-in-the-loop controls
- Browser proxy and screenshot endpoints

## Out of Scope

- Claude Agent itself (report to the Claude Agent project)
- Third-party dependencies (report to the respective maintainer)
- Social engineering attacks

## Security Measures (v3.0.0+)

**Authentication**

- All API routes require authentication as of v3.0.0
- Session tokens use timing-safe comparison to prevent timing attacks
- httpOnly + SameSite=Strict cookies
- Token revocation on logout

**Network**

- `Access-Control-Allow-Origin` restricted to localhost — no wildcard CORS
- Browser proxy and screenshot endpoints locked to same-origin only
- Rate limiting on high-risk endpoints (file access, debug, exec)

**Data & File Access**

- Path traversal prevention on all file and memory routes (`ensureWorkspacePath()`)
- `.md`-only restriction on memory write routes
- No API keys or secrets ever exposed to client-side code
- Claude tokens are server-side only
- Diagnostic output scrubbed of sensitive data

**Agent Safety**

- Exec approval workflow — sensitive Claude exec commands require explicit human approval via in-UI modal
- Skills security scanning — every skill from the marketplace is scanned for suspicious patterns before install

**Configuration**

- Environment files are gitignored
- Config endpoints redact credentials in responses
- Example configs use placeholder keys only

## Security Audit Passes

### SEC-3 (2026-02-25)

- Completed full API audit for auth coverage; no new private route auth gaps found (`/api/config-get`, `/api/debug-analyze`, `/api/context-usage`, `/api/paths` verified authenticated).
- Added CSRF content-type enforcement (`requireJsonContentType`) to remaining POST handlers, including auth and terminal management endpoints.
- Tightened rate limiting to 10 requests/minute per IP (sliding window) on high-risk endpoints:
  - `/api/terminal-input`
  - `/api/terminal-stream`
  - `/api/restart`
  - `/api/update-check` (POST)
  - `/api/update-check` (POST)
