CVE-2018-12587
A cross-site scripting (XSS) vulnerability was found in valeuraddons German Spelling Dictionary v1.3 (an Opera Browser add-on).
Does this matter?
Lower severity and a low EPSS score (0.81%). Track it; it rarely justifies an emergency change on its own.

A cross-site scripting (XSS) vulnerability was found in valeuraddons German Spelling Dictionary v1.3 (an Opera Browser add-on). Instead of providing text for a spelling check, remote attackers may inject arbitrary web script or HTML via the ajax query parameter in the URL Address Bar.
