Расширение дает возможность всем читать платные главы на сайте remanga.org, если их уже купил один из пользователей расширения

Расширение дает возможность всем читать мангу на сайте remanga.org, если ее купил один из пользователей расширения. Основная задача - возможность поделиться любимой мангой с друзьями, с чем данное расширение отлично справляется. Принцип работы расширения: - Расширение работает только на сайте remanga.org ( и алиасах ) - Расширение отправляет данные на удаленный сервер только при открытии глав покупаемой манги - Если вы покупаете главу - она загружается на сервер разработчика - Если у вас глава нет доступа к главе глава качается с сервера разработчика и отображается у вас на странице - Если платная глава не отображается - значит ее никто не купил

2	Network Interception	critical	scripts/content.js (line 3)	The extension injects a script into the page context by abusing the `onreset` event attribute on `document.documentElement` to execute arbitrary JavaScript. This technique completely replaces the native `window.fetch`…	3.1
3	Network Interception	high	scripts/background.js (line 56)	When a paid chapter has not been purchased by the current user, the extension fetches the chapter content from the exmanga.ru server and injects it back into the API response, setting `is_bought = true` and replacing …	3.1
4	Privilege Escalation	high	scripts/background.js (line 120)	The background script registers `onMessageExternal` with the same handler as `onMessage`, and the manifest declares `externally_connectable` for remanga.org pages. This means any page matching those origins can trigge…	3.1
5	Remote Code Loading	medium	scripts/content.js (line 39)	The extension fetches its own `manifest.json` from a raw GitHub URL at runtime to check for updates, then parses and evaluates the version field from that remote resource. While the current code only reads the version…	3.1
