+# Security Policy
+
+## Reporting a Vulnerability
+
+We take security vulnerabilities in Cua seriously. If you discover a security issue, please follow the responsible disclosure process below.
+
+**Do not report security vulnerabilities through public GitHub Issues.**
+
+### How to Report
+
+Please report vulnerabilities using one of the following methods:
+
+1. **GitHub Security Advisories (preferred):** Use the [GitHub private vulnerability reporting](https://github.com/trycua/cua/security/advisories/new) feature to submit a report confidentially.
+
+2. **Email:** Send details to **team@trycua.com** with the subject line `[SECURITY] <brief description>`.
+
+### What to Include
+
+When reporting, please provide as much of the following as possible:
+
+- Type of vulnerability (e.g., command injection, privilege escalation, credential leak)
+- Component(s) affected (e.g., `computer-server`, `cua-cli`, `lume`)
+- Steps to reproduce the issue
+- Potential impact and severity
+- Any suggested mitigations
+
+### Response Timeline
+
+| Stage | Target |
+|-------|--------|
+| Initial acknowledgment | ≤ 7 days |
+| Triage and severity assessment | ≤ 14 days |
+| Fix or mitigation plan communicated | ≤ 30 days |
+| Public disclosure (coordinated) | After fix is released |
+
+We aim to acknowledge all reports within **7 days** and provide a full response within **14 days**.
+
+## Supported Versions
+
+We actively maintain security fixes for the following:
+
+| Component | Supported |
+|-----------|-----------|
+| Latest release of each package | ✅ |
+| Prior minor releases | Case-by-case basis |
+
+## Scope
+
+This policy covers the following repositories and packages:
+
+- `trycua/cua` — all packages (`cua-agent`, `cua-computer`, `cua-computer-server`, `cua-bench`, `cua-cli`, `lume`)
+
+The following are **out of scope**:
+
+- Vulnerabilities in third-party dependencies (please report upstream; we will track and patch via Dependabot)
+- Issues in forks or unofficial distributions
+- Social engineering or phishing attacks
+
+## Disclosure Policy
+
+We follow [coordinated vulnerability disclosure](https://vuls.cert.org/confluence/display/Wiki/Coordinated+Vulnerability+Disclosure+Guidance). We will:
+
+1. Confirm receipt of your report
+2. Assess impact and assign a CVE if warranted
+3. Develop and test a fix
+4. Release the fix and credit you in the release notes (unless you prefer anonymity)
+5. Publicly disclose after users have had reasonable time to update
+
+## Bug Bounty
+
+We do not currently operate a paid bug bounty program. We recognize contributors in release notes and the project README.
+
+---
+
+Thank you for helping keep Cua and its users safe.

 - Improve API documentation
 - Add tutorials or guides
 
+## Testing Requirements
+
+All new features and bug fixes **must** include tests. This is a hard requirement for pull requests to be accepted.
+
+1. **Write tests for new functionality**: Every new feature should have corresponding tests covering the expected behavior.
+2. **Write regression tests for bug fixes**: If you're fixing a bug, add a test that would have caught it.
+3. **Run the test suite before submitting**: Ensure all tests pass locally before opening a PR.

+   # Run the full test suite
+   uv run pytest

+   # Run tests for a specific package
