CVE-2021-24567
The Simple Post WordPress plugin through 1.1 does not sanitize user input when an authenticated user Text value, then it does not escape these values when outputting to the browser leading to an Authenticated Stored XSS Cross-Site Scripting issue.
Does this matter?
Lower severity and a low EPSS score (0.51%). Track it; it rarely justifies an emergency change on its own.
