Executive Summary

This vulnerability is an inappropriate implementation in the MHTML feature of Google Chrome versions prior to 148.0.7778.96. It allows a remote attacker to leak cross-origin data by convincing a user to perform specific user interface gestures on a specially crafted MHTML page.

Impact Analysis

The impact of this vulnerability is that an attacker could potentially access data from other origins (websites) that should be isolated, leading to unauthorized data leakage. This could compromise user privacy and security by exposing sensitive information through crafted MHTML content.

Mitigation Strategies

To mitigate this vulnerability, update Google Chrome to version 148.0.7778.96 or later, as the issue is fixed in that release.

Additionally, avoid interacting with untrusted MHTML pages or links that could trigger the vulnerability.
