Is Ace Script safe?

Low risk

Ace Script silently auto-updates userscripts, sends session cookies on cross-origin requests, and disables CSP on all websites.

The extension periodically fetches updated userscript code from author-supplied URLs and installs new versions without user confirmation when silent-update mode is enabled, provided the new script's declared @connect list stays within the previously approved set. When running a userscript that calls GM_xmlhttpRequest, the extension retrieves the user's session cookies for the target domain and attaches them to the outgoing request via Chrome's declarativeNetRequest API, bypassing CORS restrictions after the domain is approved once. It also globally reconfigures the Chrome user-script execution world to permit unsafe-inline and unsafe-eval, removing Content Security Policy protections on every website the user visits.

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

Shared hosts - 7 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
