CVE-2021-24897
The Add Subtitle WordPress plugin through 1.1.0 does not sanitise or escape the sub-title field (available only with classic editor) when output in the page, 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 (0.60%). Track it; it rarely justifies an emergency change on its own.
