# MySQL Server RAPID component flaw lets privileged users crash the server

A flaw in the RAPID component of MySQL Server and MySQL Cluster lets a highly privileged attacker over the network cause a hang or repeatable crash. The impact is denial of service only; the sources report no confidentiality or integrity loss.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Run `SELECT VERSION();` in MySQL and check whether it reports `9.7.0` through `9.7.3` or `26.7.0` through `26.7.1`
- For MySQL Cluster, check the `ndb_mgmd --version` output against the same version ranges

## Fix

- Upgrade MySQL Server to a release after the affected ranges listed in Oracle's advisory (the fixed version number is unknown from the sources)
- Upgrade MySQL Cluster to a fixed release (the fixed version number is unknown from the sources)
