Description Doran Moppert 2018-05-09 03:15:01 EDT

The web console and JavaScript debugger do not sanitize all output that can be hyperlinked. Both will display `chrome:` links as active, clickable hyperlinks in their output. Web sites should not be able to directly link to internal chrome pages. Additionally, the JavaScript debugger will display `javascript:` links, which users could be tricked into clicking by malicious sites.
