Is CFCA CryptoKit.NCWR Extension safe?
CFCA CryptoKit.NCWR Extension relays messages from any page on localhost or 127.0.0.1 to its installed native application, unfiltered.
The extension listens for messages from external web pages and, when asked to connect, opens a connection to a native messaging host using whatever host name the calling page supplies, with no check against an expected value. It then forwards the calling page's payload to that native application as-is and returns the native app's response to the page. Because the extension's externally_connectable list includes any page served over plain HTTP from localhost or 127.0.0.1 (not just CFCA's own site), any local web server on the machine can trigger this bridge to the native app.
