Hi Team,
We have a Sitecore project with the version 9.3 and we are using windows Solr

Many servers like TST, STG, Prod.

The above attribute is not available in our project's solr version 8.1.1.
Please advise how to fix this vulnerability.

Restrict network access to specific hosts, by setting

solr.in.sh/solr.in.cmd *-* This attribjute is not available in our project's
