Description :

able to trick a victim that was logged in to the pcsd web UI into
visiting a specially crafted URL could use this flaw to execute
arbitrary code with root privileges on the server hosting the web UI.

A race condition was found in the way the pcsd web UI backend
performed authorization of user requests. An attacker could use this
