Is Grammar Checker and Writing Assistant by Sapling safe?

Low risk

Sapling's writing assistant loads and runs unsigned code from its own server on Amazon Connect contact-center pages.

On Amazon Connect (AWS Connect) contact-center pages, the extension asks Sapling's own backend (api.sapling.ai/suggest_plugin_overrides) for a page "plugin override" and passes whatever it gets back to the page. If the response looks like a URL, a <script> tag pointing at it is added to the page; otherwise the response text is executed directly as JavaScript in the page. Sapling does not sign or verify this code before running it, so anyone able to tamper with or impersonate that request could run arbitrary script on the contact-center page.

Shared hosts - 2 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.
