Description
WordPress Core is vulnerable to Remote Code Execution in versions 4.7 through 7.1.3. This is due to predictable, web-accessible staging paths used during full-package core upgrades. This makes it possible for unauthenticated attackers to execute code on the server during the upgrade window.
