+# How to report a security issue with dqlite
+
+If you find a security issue with dqlite, the best way to report it is using
+GitHub's private vulnerability reporting. [Here][advisory] is the form to
+submit a report, and [here][docs] is the detailed documentation for the GitHub
+feature.
+
+Once you submit a report, the dqlite team will work with you to figure out
+whether there is a security issue. If so, we will develop a fix, get a CVE
+assigned, and coordinating the release of the fix. The [Ubuntu Security
+disclosure and embargo policy][policy] contains more information about what you
+can expect during this phase, and what we expect from you.
