Red Hat rates this Important.
This vulnerability is rated as Important severity because, although an attacker can achieve remote code execution by tricking a user into rendering malicious web content, execution is confined within the browser's sandbox. In Red Hat Enterprise Linux environments, chromium-browser is an optional graphical application not installed or active in default server profiles. The risk is further bounded by the requirement for direct user interaction, preventing unprompted or automated exploitation against headless infrastructure.
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
