CVE-2023-48115
SmarterTools SmarterMail 8495 through 8664 before 8747 allows stored DOM XSS because an XSS protection mechanism is skipped when messageHTML and messagePlainText are set in the same request.
Does this matter?
Lower severity and a low EPSS score (0.36%). Track it; it rarely justifies an emergency change on its own.
