CVE-2020-2137
Jenkins Timestamper Plugin 1.11.1 and earlier does not sanitize HTML formatting of its output, resulting in a stored XSS vulnerability exploitable by attackers with Overall/Administer permission.
Does this matter?
Lower severity and a low EPSS score (0.70%). Track it; it rarely justifies an emergency change on its own.
