Does this matter?

Lower severity and a low EPSS score (0.15%). Track it; it rarely justifies an emergency change on its own.

Description

Craft CMS versions from 5.0.0-RC1 before 5.10.11 contain a stored cross-site scripting vulnerability in the site name field that fails to sanitize input. Administrators can inject arbitrary JavaScript payloads in the site name that execute when other users view the control panel settings pages.
