+# Security Policy
+
+**PLEASE DON'T DISCLOSE SECURITY-RELATED ISSUES PUBLICLY, [SEE BELOW](#reporting-a-vulnerability).**
+
+## Reporting a Vulnerability
+
+If you discover a security vulnerability in Pest, please report it privately using one of the following channels:
+
+1. **GitHub Private Vulnerability Reporting** (preferred) — go to the repository's **Security** tab and click **"Report a vulnerability"**. This creates a private advisory visible only to maintainers and provides a structured workflow for triage, fix coordination, and CVE assignment.
+
+2. **Email** — send the details to Nuno Maduro at **enunomaduro@gmail.com**.
+
+All security vulnerabilities will be promptly addressed.
