Technical Analysis
This vulnerability in Google Chrome on Android versions before 152.0.7977.75 is due to incorrect authorization in the Autofill component. An attacker can exploit this by crafting a malicious HTML page that, when visited by a user, may trick the browser into revealing sensitive information stored in Autofill.

The CVSS vector is AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N, reflecting network attack vector, low complexity, no privileges required, user interaction needed, unchanged scope, and high confidentiality impact.
Potential Impact
Successful exploitation allows a remote attacker to obtain sensitive user information stored in Chrome's Autofill on Android devices. This could lead to privacy breaches and potential misuse of personal data. There is no impact on system integrity or availability. The vulnerability requires user interaction and social engineering to be effective.
