CVE-2020-10431
The way URIs are handled in admin/header.php in Chadha PHPKB Standard Multi-Language 9 allows Reflected XSS (injecting arbitrary web script or HTML) in admin/manage-templates.php by adding a question mark (?) followed by the payload.
Does this matter?
Lower severity and a low EPSS score (0.61%). Track it; it rarely justifies an emergency change on its own.
