Does this matter?

Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.

Description

Versions 6.0.0 and above, prior to 6.0.3, contain a stored Cross-Site Scripting (XSS) vulnerability, where user-controlled data is rendered without proper HTML escaping.
