CVE-2019-16991
In FusionPBX up to v4.5.7, the file app\edit\filedelete.php uses an unsanitized "file" variable coming from the URL, which is reflected in HTML, leading to XSS.
Does this matter?
Lower severity and a low EPSS score (0.80%). Track it; it rarely justifies an emergency change on its own.
