Is CSOD LXP safe?

Low risk

CSOD LXP embeds hardcoded decryption keys and fetches its environment config from widgets-common-service.edcast.ai.

The extension, a learning-platform widget, ships a fixed password and Filestack decryption keys inside its bundle. It uses the password to decrypt configuration secrets fetched from its vendor's config service, and the Filestack keys to sign requests to the Filestack CDN. Because the keys are the same for every installer, anyone who reads the extension files can recover them.

Shared hosts - 5 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
