Hi Stefan,

Does December 2019 CU for SP2010 include the fix for search mentioned in here?
https://blog.stefan-gossner.com/2019/11/12/november-2019-cu-for-sharepoint-2010-product-family-is-available-for-download/

We want to apply the fix for this vulnerability “CVE-2019-1491” and we want to make sure it does break the search.

Thanks
