CVE-2021-24855
The Display Post Metadata WordPress plugin before 1.5.0 adds a shortcode to print out custom fields, however their content is not sanitised or escaped which could allow users with a role as low as Contributor to perform Cross-Site Scripting attacks
Does this matter?
Lower severity and a low EPSS score (0.62%). Track it; it rarely justifies an emergency change on its own.
