Is Open In IINA safe?

Medium risk

Open In IINA injects page-controlled URLs into browser-executed JavaScript when opening media links.

When a user invokes Open In IINA from the toolbar, popup, or context menu, the extension builds a JavaScript string from the active tab, link, or media URL and runs it in the tab. A specially crafted URL can break out of that string and execute page-supplied JavaScript in the page context.
