    Contributed by Paul Ryan —

    Note that locate_template() does not prevent directory traversal attacks, so if you’re passing a user-provided template name to the function, be sure to verify that it’s from one of the three appropriate locations (active theme directory, parent theme directory, or /wp-includes/theme-compat/ directory).

    Example:

    $template = locate_template( $template_filename_from_unsanitized_user_input );

// Only allow templates that are in the active theme directory, parent theme
// directory, or the /wp-includes/theme-compat/ directory (prevent directory 
// traversal attacks).
$template_in_theme_or_parent_theme_or_compat = (
	// Template is in current theme folder.
	0 === strpos( realpath( $template ), realpath( STYLESHEETPATH ) ) ||
	// Template is in current or parent theme folder.
	0 === strpos( realpath( $template ), realpath( TEMPLATEPATH ) ) ||
	// Template is in theme-compat folder.
	0 === strpos( realpath( $template ), realpath( ABSPATH . WPINC . '/theme-compat/' ) )
);

if ( $template_in_theme_or_parent_theme_or_compat ) {
	require_once( $template );
}
