Is JSON Viewer safe?

Low risk

JSON Viewer renders URL values from JSON pages into link attributes without escaping the URL.

The content script runs on all URLs at document start, but it only formats pages that look like JSON or JSONP. It passes the page's raw JSON to the extension formatter, then replaces the page body with generated HTML; URL-like string values are inserted directly into href attributes, so crafted JSON can become page HTML.
