Impact

An observable discrepancy in the Controls component of Google Chrome prior to version 156.0.8078.47 allows a remote attacker who lures a user to a crafted HTML page to obtain sensitive information. The vulnerability arises from improper handling of control data, leading to information exposure. This issue is classified as CWE‑203, which denotes information exposure through logical oversight.

Affected Systems

All installations of Google Chrome before version 156.0.8078.47 are susceptible. The vulnerability exists in the desktop releases of the browser. Chrome 156.0.8078.47 and later contain the remedial changes.
