Unified Remote 3.13.0 allows remote attackers to execute arbitrary Lua code because of a wildcarded Access-Control-Allow-Origin for the Remote upload endpoint.

Because the web management interface for Unified Intents' Unified Remote solution does not itself require authentication, a remote, unauthenticated attacker can change or disable authentication requirements for the Unified Remote protocol, and leverage this now-unauthenticated access to run code of the attacker's choosing.
