Is Bambboo safe?

Bambboo reads your LinkedIn session cookie and returns it to the Bambboo web app so its servers can act under your LinkedIn login.

When the Bambboo web app sends the extension a request, its service worker reads your LinkedIn li_at session cookie via the cookies permission and returns the raw value to the app. This lets Bambboo's own servers make LinkedIn requests under your logged-in session. Cookie access is limited to LinkedIn by host permissions, and only Bambboo's own sites (app.bambboo.com and *.bambboo.jobinlive.fr) are allowed to request it.
