Is Ziflow - Review and Approval safe?

Low risk

Ziflow lets any web page request a screenshot of the visible tab and strip frame and CSP headers.

The extension's content script, injected on all pages, answers a page-level message by capturing a PNG of the visible tab and posting it back, once the page creates a marker element. The same marker also makes the background script remove X-Frame-Options and Content-Security-Policy headers from that tab's responses and optionally rewrite cookies to SameSite=None. No origin check limits these requests to Ziflow's own pages.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.
