CVE-2021-31412
Improper sanitization of path in default RouteNotFoundError view in com.vaadin:flow-server versions 1.0.0 through 1.0.14 (Vaadin 10.0.0 through 10.0.18), 1.1.0 prior to 2.0.0 (Vaadin 11 prior to 14), 2.0.0 through 2.6.1 (Vaadin 14.0.0 through 14.6.1),…
Does this matter?
Lower severity and a low EPSS score (1.32%). Track it; it rarely justifies an emergency change on its own.
