 ### 2.14.18
 
+* [Issue 10262](https://bugs.chromium.org/p/gerrit/issues/detail?id=10262):
+Upgrade JGit to 4.7.7.201812240805-r to fix validation of `wants` in
+`git-upload-pack` for protocol v0 bidirectional transports.
+
+  AdvertiseRefsHook was not called for `git-upload-pack` in protocol v0
+  bidirectional transports, meaning that `wants` were not validated and
+  a user could fetch anything that is pointed to by any ref (using fetch-by-sha1),
+  as long as they could guess the object name.
+
+* [Issue 10242](https://bugs.chromium.org/p/gerrit/issues/detail?id=10242):
+Fix regression that allows a user's account to be taken over when multiple
+authentication providers are in use.
+
+  A regression introduced in 2.14.7 allowed a user's account to be taken
+  over by creating an account on a different provider with exactly the same
+  username as the existing Gerrit account.

 * [Issue 10112](https://bugs.chromium.org/p/gerrit/issues/detail?id=10112):
 Upgrade rules_closure to make Gerrit buildable with the latest Bazel version.
