CVE-2018-5233
Cross-site scripting (XSS) vulnerability in system/src/Grav/Common/Twig/Twig.php in Grav CMS before 1.3.0 allows remote attackers to inject arbitrary web script or HTML via the PATH_INFO to admin/tools.
Does this matter?
Lower severity and a low EPSS score (3.65%). Track it; it rarely justifies an emergency change on its own.
