DOM-based link manipulation
Summary: DOM-based link-manipulation vulnerabilities arise when a script writes attacker-controllable data to a navigation target within the current page, such as a clickable link or a form's submission URL. An attacker can construct a URL that, when visited by another user, modifies the target of links within the response.
What you should know: A crafted link can silently redirect other users' clicks and form submissions to a destination the attacker chooses, and PortSwigger's guidance is to never let untrusted data set link or form targets dynamically.
