+## Reporting a Vulnerability
+
+If you think you've identified a security issue in any Docling project repository, please DO NOT report the issue publicly via the GitHub issue tracker, etc.
+
+Instead, send an email with as many details as possible to [deepsearch-core@zurich.ibm.com](mailto:deepsearch-core@zurich.ibm.com). This is a private mailing list for the maintainers team.
+
+Please do not create a public issue.
+
+### Security Vulnerability Response
+
+Each report is acknowledged and analyzed by the core maintainers within 3 working days.
+
+Any vulnerability information shared with core maintainers stays within the Docling project and will not be disseminated to other projects unless it is necessary to get the issue fixed.
+
+After the initial reply to your report, the security team will keep you informed of the progress towards a fix and full announcement, and may ask for additional information or guidance.
+
+## Security Alerts
+
+We will send announcements of security vulnerabilities and steps to remediate on the [Docling announcements](https://github.com/docling-project/docling/discussions/categories/announcements).
