Hi Guys!
We are facing troubles with workflows using on-premises SharePoint 2013. These are default SharePoint 2010 processes. Does someone know about this issue? They are failed to start and the system says that it was cancelled by System Account.
Before Monday it was working perfectly.

Click on Microsoft Support link on how to repair the workflow issue after applying CVE-2018-8241 September 2018 update. There are changes needed in web.config on each Web application.
Error log entry:
System.CodeDom.CodeBinaryOperatorExpression is not marked as authorized in the application configuration file.
