CVE-2020-5296
In OctoberCMS (october/october composer package) versions from 1.0.319 and before 1.0.466, an attacker can exploit this vulnerability to delete arbitrary local files of an October CMS server.
Does this matter?
Lower severity and a low EPSS score (1.43%). Track it; it rarely justifies an emergency change on its own.
