This vulnerability involves a use-after-free condition in the Navigation functionality of Google Chrome before version 149.0.7827.103. Exploitation could enable a remote attacker to perform a sandbox escape through a specially crafted HTML page. The issue was publicly disclosed on June 8, 2026, and is rated high severity by Chromium security. The vendor has released an update to address this vulnerability as indicated in the official Chrome stable channel update advisory.

Successful exploitation of this vulnerability could allow a remote attacker to escape the Chrome sandbox, potentially leading to execution of arbitrary code outside the browser's restricted environment. This elevates the risk of further system compromise beyond the browser context. However, no active exploitation has been reported so far.

Google has released a stable channel update for Chrome version 149.0.7827.103 that addresses this vulnerability. Users and administrators should update affected Chrome installations to this version or later to remediate the issue. Since this is a client-side application, patching is the primary mitigation. No additional vendor-recommended mitigations are indicated in the advisory.
