Mozilla Firefox allows cross-domain access to an iframe. This vulnerability could allow an attacker to interact with a web site in a different domain. The attacker could read content and cookies, capture keystrokes, and modify content.
An iframe is an HTML element which allows an HTML document to be embedded inside a master HTML document.
The Mozilla same origin policy states:
An attacker may be able to obtain sensitive data from a user, modify the appearance of a webpage or track keystrokes. Depending on the nature of the web site the user was visiting, this data may include passwords, credit card numbers, and any arbitrary information provided by the user.
Mozilla has addressed this issue with Firefox 126.96.36.199. Please see Mozilla Foundation Security Advisory 2007-20 for details.
