Better readable file:
https://github.com/jenkinsci/jenkins/blob/master/war/src/main/webapp/scripts/yui/connection/connection-debug.js#L1046

It's part of the YUI library and used to enable cross-domain requests.

According to 
https://helpx.adobe.com/flash-player/kb/changes-allowscriptaccess-default-flash-player.html
 doing this requires AllowScriptAccess 'always'.

I'm not a Flash expert, but as the SWF file used here is connection.swf from 
the same library (YUI) and should be trusted, and any embedding only happens 
for deliberate cross-domain requests, this doesn't seem to be a real issue.

If you have further information that shows this is an actual problem, please 
submit a report with further information to the SECURITY project in Jira.
