CVE-2017-9451
Cross site scripting (XSS) vulnerability in pages.edit_form.php in flatCore 1.4.6 allows remote attackers to inject arbitrary JavaScript via the PATH_INFO in an acp.php URL, due to use of unsanitized $_SERVER['PHP_SELF'] to generate URLs.
Does this matter?
Lower severity and a low EPSS score (0.74%). Track it; it rarely justifies an emergency change on its own.
