+# Security Policy
+
+## Scope
+
+cc-manager is a **local development tool**. It is designed to run on a developer's machine or within a trusted internal network. It has no authentication and should **never** be exposed to the public internet.
+
+## Known Limitations
+
+| Area | Status | Mitigation |
+|------|--------|------------|
+| Authentication | None | Local use only; restrict via firewall or reverse proxy |
+| CORS | Open (all origins) | Restrict at reverse proxy level if needed |
+| Webhook SSRF | Partial — blocks private/loopback IPs | DNS rebinding not prevented; use trusted endpoints only |
+| Rate limiting | Static key (`"direct"`) | Does not trust `x-forwarded-for`; add `--trust-proxy` if behind proxy |
+
+## Reporting a Vulnerability
+
+If you discover a security issue, please report it privately:
+
+1. **Do NOT open a public issue.**
+2. Email the maintainers or use [GitHub Security Advisories](https://github.com/agent-next/cc-manager/security/advisories).
+3. Include steps to reproduce and potential impact.
+4. We will respond within 7 days.
+
+## Security Controls
+
+- **Webhook URL validation**: Blocks loopback, RFC 1918 private ranges, and link-local addresses.
+- **Rate limiting**: 30 requests/minute per client on task submission endpoints.
+- **Input validation**: Prompt length limits, timeout bounds, priority enum enforcement.
+- **Agent isolation**: Each agent runs in an isolated git worktree. `CLAUDECODE` and `CLAUDE_CODE_*` env vars are cleared to prevent Claude nesting.
+- **SQLite WAL mode**: Prevents database corruption under concurrent access.
