CVE-2019-16990
In FusionPBX up to v4.5.7, the file app/music_on_hold/music_on_hold.php uses an unsanitized "file" variable coming from the URL, which takes any pathname (base64 encoded) and allows a download of it.
Does this matter?
Lower severity and a low EPSS score (1.28%). Track it; it rarely justifies an emergency change on its own.
