Blocking of Requests Due to Salesforce Origin Shielding

Salesforce is making a series of changes to protect the Commerce Cloud instance origin, due to but not limited to mitigating the risk of malicious traffic to the origin. As a consequence of this specific traffic to endpoints on the origin (hosts ending with *.demandware.net) will be blocked unless explicitly whitelisted. See more details in the general announcement at https://help.salesforce.com/s/articleView?id=000364472&type=1

The CLIs commands making Data API requests are being impacted by that, as in general Data API requests made to the origin through *.demandware.net hostnames are being blocked.

However, the CLI commands are being whitelisted for requests made against development instances. As a consequence, you don't have to change any of the build scripts related to CLI commands, in case you are integrating with development instances.
