Volto affected by possible DoS by invoking specific URL by anonymous user
Impact
When visiting a specific URL, an anonymous user could cause the NodeJS server part of Volto to quit with an error.
Patches
The problem has been patched and the patch has been backported to Volto major versions down until 16. It is advised to upgrade to the latest patch release of your respective current major version:

- Volto 18: 18.24.0
