Chrome browser extensions can steal passwords from the text input fields in websites, despite Chrome's latest security and privacy standard, Manifest V3.
Researchers at the University of Wisconsin–Madison found that Chrome browser extensions can still steal passwords, despite compliance with Chrome’s latest security standard, Manifest V3.
A proof of concept extension successfully passed the Chrome Web Store review process, demonstrating the vulnerability.
The core issue lies in the extensions’ full access to the Document Object Model (DOM) of web pages, allowing them to interact with text input fields like passwords.
Analysis of existing extensions showed that 12.5% had the permissions to exploit this vulnerability, identifying 190 extensions that directly access password fields.
Researchers propose two fixes: a JavaScript library for websites to block unwanted access to password fields, and a browser-level alert system for password field interactions.

Nothing really. The way add-ons interact with web pages is very similar.
Yeah. That’s why I don’t understand how using Firefox would be solution to this. The only solution is to not use extensions.
