Facebook’s Pete Bratach posted a note tonight regarding a recent notice from the Adobe Flash team that an upcoming April update to the Flash Player could break many Facebook applications. The security update significantly affects cross-domain functionality and could affect a large number of apps that use Flash.
Specifically, if any of the following apply to your app, you will be affected by the update:
- You use sockets or XMLSockets, regardless of the domain to which you are connecting
- You use addRequestHeader or URLRequest.requestHeaders in any network API call when sending or loading data cross-domain
- You provide access to content on remote domains as a web service provider
- You have SWFs that are exported for Flash Player 7 (SWF7) or earlier that communicate with the hosting HTML by any means
