Is Gléas CertImporter Extension safe?

Low risk

Gleas CertImporter PKI bridges certificate and token operations on vendor PKI pages to a locally installed native app via native messaging.

On pages matching vendor-specific PKI URL patterns (certificate import, token import/init, and login flows), the extension relays messages between the page and the locally installed com.jcch_sss.certimporter application using Chrome's native messaging API. Responses from the native app are forwarded back to the page via window.postMessage with a wildcard targetOrigin, meaning any script on the page can read the response payload. The extension does not communicate with any remote servers; all data flow is between the browser page and the local native application.

Where it sends data

Destinations our analysis observed Gléas contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.

  • com.jcch_sss.certimporter (local native app)

    Gléas sends data to com.jcch_sss.certimporter (local native app). Named as a recipient in this extension's own analysis.
