Question for bitrix programmers: how did you solve problems with Cross-Site Scripting?

Question

1C-Bitrix

Launched a security scanner that revealed problems of this kind

Cross-Site Scripting
File: /home/bitrix/ext_www/sitename/bitrix/templates/market_column_1/bxready/library/elements/ecommerce_v1/element.php

303: echo $_COOKIE['_ym_uid']
Необходимые условия:
90: if($arElement['IBLOCK_SECTION_ID'] !== "869")
Аналогично:
311: echo $_COOKIE['_ym_uid']
319: echo $_COOKIE['_ym_uid']

and the static analyzer dug up 10 such jambs.

What does this mean and how do you deal with it?

ps: I wish you all good health, a lot of love and money, and not to face Bitrix yet

Answer 1

You are parsing a third party custom template, not the core, so the question should be addressed to them.
