How can hidden HTML code in product descriptions be identified and removed?

Hi all,

We have noticed that a coding was hidden in our listing’s HTML.

  1. Can we understand how this HTML input of “promfflinkdev” be added to the product description? The URL is being flagged as malicious by our security team and the security vendors.
  2. Can Shopify identify and remove the above-mentioned link/tag from all products within our shop/ website?

Thank you.
