Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Vitess versions before 0.16.2 are affected: VTAdmin users who can create shards can create one whose name contains "/" characters, after which VTAdmin rejects new shard creation and fails to show keyspaces. An attacker needs a VTAdmin account with permission to create shards, and the effect is denial of access to those functions for other users. Upgrade to Vitess 0.16.2 or later. Until then, create shards with vtctldclient instead of VTAdmin, or disable shard creation in VTAdmin using RBAC.
