Summary
Cross-site Scripting (XSS) possible due to improper sanitisation of `href` attributes on `<a>` tags
Details

Summary

There is a potential cross-site scripting (XSS) vulnerability that can be exploited via maliciously crafted user data.

Our filter to detect and prevent the use of the javascript: URL scheme in the href attribute of an <a> tag could be bypassed with tab \t or newline \n characters between the characters of the protocol, e.g. java\tscript:.

a(href: user_profile) { "Profile" }
