Trusted URLs
From VRChat Wiki
It is written and maintained by VRCWiki Team.
By default, worlds in VRChat cannot make requests to untrusted URLs unless the user enables the "Allow Untrusted URLs" setting. Public instances are additionally secured by a list of up to 10 hosts, which can be set by the world creator. This is an intentional measure for security purposes. There is however an allowlist of trusted domains that are the exception to this rule, and are specific to the type of content being loaded. Below are the different allowlists by type.
