CVE-2023-6433
A vulnerability has been discovered in BigProf Online Invoicing System 2.6, which does not sufficiently encode user-controlled input, resulting in persistent XSS through /inventory/suppliers_view.php, in the FirstRecord parameter.
Does this matter?
Lower severity and a low EPSS score (0.39%). Track it; it rarely justifies an emergency change on its own.
