The Autofill implementation in Google Chrome versions before 151.0.7922.72 contains a flaw that permits a remote attacker to leak data across origins by crafting a malicious HTML page. This cross-origin data leak could expose sensitive information that Autofill manages. The vulnerability is specific to the Autofill feature and does not have a disclosed CVSS score or detailed exploitation methods. No patch links are provided in the data, but the fixed version is identified as 151.0.7922.72 or later.

Successful exploitation could lead to unauthorized disclosure of cross-origin data managed by the Autofill feature in affected Chrome versions. This could compromise user privacy by leaking sensitive autofill information to an attacker-controlled page. There is no indication of code execution or broader system compromise from the provided data.

Users and administrators should update Google Chrome to version 151.0.7922.72 or later to remediate this vulnerability. Since the affected versions are prior to 151.0.7922.72, applying this official fix eliminates the risk. No additional mitigation guidance or temporary workarounds are provided.
