Browser page caching is a way for web browsers to store copies

I am currently investigating how Internet Explorer caches page content (such as input and textarea) in the browsing history.

Steps taken:

User visits Page1 with a textarea, then navigates to Page2, and returns to Page1 where the textarea data is automatically filled in by the browser.

If malicious code is inserted into the textarea, it can be executed by Angular and result in a XSS attack.

My goal is to sanitize the data before it is stored in the browsing history. Any insights or suggestions on this matter would be greatly appreciated.

Answer №1

I haven't come across any official documentation that specifically outlines how Internet Explorer stores field data in its cache. However, I have found some informative articles on the topic that you may find helpful.

  1. Understanding Microsoft Internet Explorer Cache

  2. Ie caching form data

Additionally, I have not been able to locate a document that delves deeply into field-level caching explanations.

I recognize your interest in sanitizing cached data and suggest validating fields as a measure to prevent users from inserting malicious code.
