CVE-2026-79110
Description
A flaw was found in chromium-browser. This missing authorization vulnerability in the Preload component allows a remote attacker to bypass the web origin policy by tricking a user into opening a specially crafted HTML page. This could lead to unauthorized access to sensitive information or actions within the browser's security boundaries.
Statement
Red Hat rates this vulnerability as Important because an unauthenticated remote attacker can bypass same-origin security boundaries and access confidential cross-origin data. While triggering the flaw requires a user to load a malicious web page, the ability to breach domain isolation elevates the risk beyond Moderate. Chromium is not distributed in supported Red Hat Enterprise Linux channels, and exposure is limited to community environments such as EPEL and Fedora.
