Description
Impact
Users can either intentionally or inadvertently create a shard containing / characters from VTAdmin such that from that point on, anyone who tries to create a new shard from VTAdmin will receive an error.
Attempting to view the keyspace(s) will also no longer work.
Creating a shard using vtctldclient does not have the same problem because the CLI validates the input correctly.
Patches
v16.0.2, corresponding to 0.16.2 on pkg.go.dev
Workarounds
- Always use
vtctldclient to create shards, instead of using VTAdmin
- Disable creating shards from VTAdmin using RBAC
- Delete the topology record for the offending shard using the client for your topology server. For example, if you created a shard called
a/b in keyspace commerce, and you are running etcd, it can be deleted by doing something like
% etcdctl --endpoints "http://${ETCD_SERVER}" del /vitess/global/keyspaces/commerce/shards/a/b/Shard

NVD description
Vitess is a database clustering system for horizontal scaling of MySQL through generalized sharding. Prior to version 16.0.2, users can either intentionally or inadvertently create a shard containing `/` characters from VTAdmin such that from that point on, anyone who tries to create a new shard from VTAdmin will receive an error. Attempting to view the keyspace(s) will also no longer work. Creating a shard using `vtctldclient` does not have the same problem because the CLI validates the input correctly. Version 16.0.2, corresponding to version 0.16.2 of the `go` module, contains a patch for this issue. Some workarounds are available. Always use `vtctldclient` to create shards, instead of using VTAdmin; disable creating shards from VTAdmin using RBAC; and/or delete the topology record for the offending shard using the client for your topology server.
