Description Zack Miele 2024-05-08 15:24:36 UTC 
Vitess is a database clustering system for horizontal scaling of MySQL. When executing the following simple query, the `vtgate` will go into an endless loop that also keeps consuming memory and eventually will run out of memory. This vulnerability is fixed in 19.0.4, 18.0.5, and 17.0.7.
