AI Analysis
Technical Summary
This vulnerability involves an inappropriate implementation in the network component of Google Chrome before version 151.0.7922.72. It enables a remote attacker to leak cross-origin data by crafting a malicious HTML page, violating the same-origin policy. The CVSS 3.1 base score is 4.3 (medium), reflecting a network attack vector with low complexity and no privileges required but requiring user interaction. The impact is limited to confidentiality loss without affecting integrity or availability.
Potential Impact
An attacker can remotely cause information disclosure of cross-origin data, potentially exposing sensitive user information accessible via the browser. The vulnerability does not allow code execution, integrity modification, or denial of service. No active exploitation has been reported.
