Vitess is a database clustering system for horizontal scaling of MySQL. In 24.0.2 and earlier, the /debug/vrlog endpoint registered by addHttpEndpoint() in go/vt/vttablet/tabletmanager/vreplication/vrlog.go invokes vrlogStatsHandler() without acl.CheckAccessHTTP(r, acl.DEBUGGING), unlike comparable debug endpoints. A remote caller who can reach the vttablet debug HTTP port can bypass the configured security policy and stream VrLogStats data produced from NewVrLogStats().Send(), including literal SQL statements and bound application values from MoveTables, Reshard, Materialize, and vitess-strategy Online DDL workflows
