## AI overview

This article explains DOM clobbering, a condition in which HTML element IDs or name attributes conflict with global JavaScript variables or functions. It describes how browsers create global variables from these attributes, how conflicts can overwrite existing functions, and how attackers may exploit the behavior to cause unpredictable behavior or security vulnerabilities such as cross-site scripting (XSS).
