How to fix?

Upgrade faye to version 0.8.9 or higher.


faye is a simple pub/sub messaging for the web. Affected versions of the package are vulnerable to Man-In-The-Middle attacks due to insecure defaults. By default, faye used an insecure cipher, allowing attackers to gain access to SSL encrypted packets. This attack is also known as the BEAST attack.
