CVE-2026-41846
Spring MVC applications which accept user-supplied values in the cssClass, cssErrorClass, or cssStyle attributes of JSP form tags allow arbitrary HTML/JavaScript code injection, potentially resulting in a cross-site scripting (XSS) vulnerability.
Does this matter?
Lower severity and a low EPSS score (0.15%). Track it; it rarely justifies an emergency change on its own.
