CVE-2020-29555: Getgrav Grav CMS

High severity, CVSS 8.1. EPSS: 2.9% chance of exploitation in the next 30 days.

The BackupDelete functionality in Grav CMS through 1.7.0-rc.17 allows an authenticated attacker to delete arbitrary files on the underlying server by exploiting a path-traversal technique. (This vulnerability can also be exploited by an unauthenticated attacker due to a lack of CSRF protection.)
