raw("<b>Welcome</b>")Why it matters & how to fix it
Request-controlled data is marked HTML-safe via raw()/html_safe/ content_tag, bypassing Rails auto-escaping and enabling cross-site scripting (CWE-79). Render user data through normal ERB output (<%= %>) so it is escaped, and only mark output safe after sanitizing with the Rails sanitize helper and an allow-list.
