faye@0.8.1 vulnerabilities

faye is a simple pub/sub messaging for the web.

Upgrade faye to version 1.4.0 or higher.

faye is a simple pub/sub messaging for the web.

Affected versions of this package are vulnerable to Improper Access Control. The Server parses channels in a way that means any channel namespaced under /meta/subscribe will also work as a subscription request. For example if the client sends a message to the channel /meta/subscribe/x, that will bypass most authentication extensions but will still be interpreted by the server as a subscription request, and the client will be subscribed to the requested channel. The client has thus bypassed the user's access control policy.

Upgrade faye to version 1.0.4, 1.1.3, 1.2.5 or higher.
