Google Chrome Reading Mode may bypass site isolation

CVE-2026-110160 · published 22 days ago
Summary

In versions of Google Chrome before 155.0.8059.79, the Reading Mode feature does not properly check whether a page is allowed to use it. An attacker who already controls part of the browser could craft a special web page that tricks Chrome into breaking its normal separation of sites, potentially exposing data from other sites. Update Chrome to the latest version to fix the issue.

What to do
