 ## Bugfix Releases
 
+### 2.14.22
+
+* Security Fixes
+
+  * [Issue 13514](https://bugs.chromium.org/p/gerrit/issues/detail?id=13514):
+  Work around Gitiles bug on `All-Users` visibility.
+
+    Gitiles has a special `FilteredRepository` wrapper that allows carefully
+    hiding refs based on the project's ACLs. There is however an optimization
+    that skips the filtering in case a user has `READ` permissions on every ACL
+    pattern(s). When the target repository is `All-Users`, the optimization
+    turns into a security issue because it allows seeing all personal information
+    associated with all accounts, i.e.:
+
+    * draft comments
+    * draft edits
+    * personally identifiable information (PII) of all users
+    * external ids
+
+    This fix now blocks Gitiles or any other part of Gerrit to abuse this power
+    when the target repository is `All-Users`, where nobody can be authorized
+    to skip the ACLs evaluation anyway.
