CVE-2018-18307
A Stored XSS vulnerability has been discovered in version 4.1.0 of AlchemyCMS via the /admin/pictures image field.
Does this matter?
Lower severity and a low EPSS score (1.70%). Track it; it rarely justifies an emergency change on its own.
Description
A Stored XSS vulnerability has been discovered in version 4.1.0 of AlchemyCMS via the /admin/pictures image field. NOTE: the vendor's position is that this is not a valid report: "The researcher used an authorized cookie to perform the request to a password-protected route. Without that session cookie, the request would have been rejected as unauthorized."
