CVE-2019-16986
In FusionPBX up to v4.5.7, the file resources\download.php uses an unsanitized "f" variable coming from the URL, which takes any pathname and allows a download of it.
Does this matter?
Lower severity and a low EPSS score (1.41%). Track it; it rarely justifies an emergency change on its own.
