CVE-2019-19133
The CSS Hero plugin through 4.0.3 for WordPress is prone to reflected XSS via the URI in a csshero_action=edit_page request because it fails to sufficiently sanitize user-supplied input.
Does this matter?
Lower severity and a low EPSS score (1.88%). Track it; it rarely justifies an emergency change on its own.
Description

An attacker may leverage this issue to execute arbitrary JavaScript in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookies or launch other attacks.
