+ * [Security Announcements](#Security-Announcements)

+
+## Supported Versions
+
+We support both the most recent stable release series (1.x) and
+the current development release series (2.x).
+
+## Signed Releases
+
+All commits and releases (the files on ftp.gnu.org) are signed by a
+maintainer.  Each maintainer uses their personal GPG key known to and
+verified by the GNU project.
+
+## Reporting a Vulnerability
+
+If you think you've identified a security issue in GNU libmicrohttpd, please
+**do not** report the issue publicly via a mailing list, IRC, a public issue on
+the GitLab issue tracker, a merge request, or any other public venue.
+
+Instead, report a [*confidential* ("private") issue in the Mantis
+issue tracker](https://bugs.gnunet.org/set_project.php?project_id=10)]
+with the “private” box checked. Please include as many details as
+possible, including ideally a minimal reproducible example of the
+issue, and an idea of how exploitable/severe you think it is.
+
+Private issues are only visible to the reporter and the core developer
+team.
+
+The next steps are then:
+ * The report is triaged.
+ * Code is audited to find any potential similar problems.
+ * The fix is prepared for the development branch, and for the most recent
+   stable branch.
+ * The fix is submitted to the public repository and a new release
+   containing the fix is issued.
+ * On the day the issue and fix are made public, an announcement is made on the
+   [public channels listed below](#Security-Announcements).
+
+As per the [GNU security processes](https://www.gnu.org/software/security/)
+you may escalate the report with the GNU project if -- for any reason -- the
+GNU libmicrohttpd maintainers are unable to respond in a timely fashion.
+
+
+## Security Announcements
+
+Security announcements are made publicly via the
+[GNU libmicrohttpd mailinglist](https://lists.gnu.org/mailman/listinfo/libmicrohttpd).
