Technical Analysis
This vulnerability involves incorrect authorization in the WebXR feature of Google Chrome versions prior to 152.0.7977.65. An attacker can exploit this by tricking a user into visiting a maliciously crafted HTML page, which then allows the attacker to access data from other origins, violating the same-origin policy. The CVSS v3.1 base score is 6.5, reflecting a medium severity with network attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, high confidentiality impact, and no impact on integrity or availability.
Potential Impact
Successful exploitation can lead to unauthorized disclosure of cross-origin data, potentially exposing sensitive information to remote attackers without requiring prior access or privileges. The attack requires user interaction (social engineering) but can result in high confidentiality impact.
