Blade prevents many cross-site scripting risks by HTML-encoding values displayed with its standard {{ }} echo syntax. If a user submits text containing script tags, the tags are rendered as text rather than executed by the browser.

This protection applies only when the escaped syntax is used correctly. Developers must avoid raw {!! !!} output for untrusted data, sanitize HTML when rich content is intentionally allowed, and continue to use context-appropriate escaping for JavaScript, URLs, CSS, and attributes.
