Not that I know of, but you could create your own. Though I have not looked,
but I would be very surprised if cflib.org did not already have a function for
this
This could certainly be improved ...
<cfset list1 = "a,b,c,d,e,f,g,h,i">
<cfset list2 = "1,b,2,3,e,6,9">
<cfset shared = "">
<cfloop list="#list1#" index="elem">
<cfif listFindNoCase(list2, elem)>
<cfset shared = listAppend(shared, elem)>
</cfif>
</cfloop>
<cfoutput>
shared = #shared#<br>
</cfoutput>
