Hello Everyone ! Here’s is my write-up BUG “HTML INJECTION” On Tokopedia
What is HTML Injection?
Hypertext Markup Language (HTML) injection is a technique used to take advantage of non-validated input to modify a web page presented by a web application to its users. Attackers take advantage of the fact that the content of a web page is often related to a previous interaction with users.
