2	Code Injection	critical	serwice-worker.js (line 420)	Scriptlets fetched from the operator's remote server are injected into every visited webpage using `world: 'MAIN'`, which means they execute in the same JavaScript context as the page itself — with full access to page…	3.0.14
3	Remote Code Loading	critical	serwice-worker.js (line 357)	The extension fetches a fully dynamic rule set from the operator's server every hour, identified by the per-installation UID. The server response controls which CSS rules, extended CSS rules, and JavaScript scriptlets…	3.0.14
4	Remote Code Loading	critical	serwice-worker.js (line 320)	The scriptlet rule list is fetched as raw text from a URL (`data.url`) returned by the remote rules API, meaning the operator controls not just which scriptlets run but also where the scriptlet definitions are hosted.…	3.0.14
5	Code Injection	high	manifest.json (line 27)	Content scripts run at `document_start` on every frame of every URL (`:///*`, `match_about_blank: true`, `all_frames: true`), which triggers the service worker's `invokeScriptlets`, `insertCss`, and `invokeApplyExtC…	3.0.14

7	Privilege Escalation	high	manifest.json (line 19)	The `externally_connectable` manifest key grants any page on `*.supremeadblocker.com` the ability to send messages directly to the extension via `chrome.runtime.sendMessage`. This provides the operator's website with …	3.0.14
8	Remote Code Loading	high	serwice-worker.js (line 432)	The extension periodically pulls a server-controlled rule manifest from `supremeadblocker.com` and immediately trusts server-provided CSS, extended CSS, scriptlet, and network-rule update endpoints. This gives the ope…	3.0.16

10	Remote Code Loading	medium	serwice-worker.js (line 141)	CSS rules are fetched from a URL supplied by the remote server's response — the extension does not use a hardcoded filter list URL. This means the operator can redirect rule fetches to any server at any time, changing…	3.0.14
