What are security considerations for DOM clobbering?

DOM clobbering is a technique that exploits the HTML DOM tree to overwrite existing properties or methods in the global scope, leading to potential security vulnerabilities. When developers inadvertently allow user input to define IDs or names, it can be easy for malicious actors to manipulate these properties. Security considerations for DOM clobbering include:

• Input Validation: Always validate and sanitize user input to prevent unintended modifications to the DOM.
• Use Unique Identifier Names: Ensure that IDs and names used in the HTML are unique and do not conflict with global properties.
• Restrict Object Exposure: Limit the exposure of global variables and objects to minimize the attack surface.
