Hi everyone,

I have discovered that SWFUpload, the Flash-based backend that we use for the 
Uploader on legacy (i.e. old Internet Explorer) browsers, has an unpatched 
cross-site scripting vulnerability. I’ve filed a JIRA ticket about this issue 
here:

http://issues.fluidproject.org/browse/FLUID-5354

SWFUpload has, sadly, always represented some of the worst and most brittle 
code we’ve encountered. Replacing it is costly, and time are changing. Our plan 
for post-1.5 has been to drop support for legacy (i.e. non latest version) 
browsers. This would have involved removing Flash support in the Uploader 
anyway.

Given the severity of this issue, I am proposing that we go ahead and drop 
Flash support from the Uploader in the Infusion 1.5 release. On legacy browsers 
such as IE 8 and 9, the simple file uploader will be delivered instead. Modern 
browsers will get the feature-rich HTML5 version.
