The extension popup loads its entire UI from an external HTTP URL over an unencrypted connection. This means any network-level attacker (or the publisher by updating the remote page) can silently inject arbitrary HTML/JavaScript into the extension popup without pushing a new CWS release. While the destination domain matches the publisher's email domain (vilsv.net), the unencrypted transport and fully-remote execution model mean the extension's behavior is not fixed by the submitted ZIP.

A mismatch between what Google shows in the store listing and what is actually installed means the declared security posture may not reflect the installed code; this discrepancy warrants scrutiny and could indicate a partial or deferred update not yet propagated to all users.
