Is ARCON Browser Extension safe?

Low risk

ARCON Browser Extension lets any web page trigger its proxy, login and SAML automation through an unchecked postMessage relay.

A content script on all http, https and file pages forwards page messages named executeJSON to the background script, checking only that the message came from the page itself, not its origin. The background then acts on the supplied configuration: it can set a proxy gateway with credentials, post credentials to a given API URL, open OIDC or AWS sign-in URLs, and inject a SAML response. The handler is built for the vendor's privileged access web console but is reachable from any site.
