+# Security Policy
+
+## Reporting a Vulnerability
+
+**Do not open a public issue for security vulnerabilities.**
+
+Use the GitHub Security Advisories feature in the affected repository to report vulnerabilities privately:
+
+1. Navigate to the affected repository (for example, `https://github.com/ui-awesome/repo-name`, replacing `repo-name`
+   with the affected repository).
+2. Go to the **Security** tab.
+3. Click **Report a vulnerability**.
+4. Provide a detailed description including steps to reproduce, impact, and any suggested fix.
+
+For more information, see [Privately reporting a security vulnerability](https://docs.github.com/en/code-security/security-advisories/guidance-on-reporting-and-writing-information-about-vulnerabilities/privately-reporting-a-security-vulnerability).
+
+## Supported Versions
+
+Security fixes are applied to the latest release of each package. Older versions do not receive security updates.
+
+## Response Timeline
+
+- **Acknowledgment**: Within 48 hours of the report.
+- **Assessment**: Within 7 days, an initial assessment and plan of action.
+- **Fix and disclosure**: A fix is developed, tested, and released before public disclosure.
+
+## Scope
+
+This policy applies to all repositories under the [ui-awesome](https://github.com/ui-awesome) organization.
