According to the SANS Internet Storm Center, a new HTTP method called Query has been introduced. This method is designed to allow GET requests that include a body, which is unusual because standard GET requests typically do not carry one.
The motivation behind Query is to resolve the ambiguity of what happens when a GET request does include a body. By providing a dedicated method, the new standard offers a clear way to handle such requests, potentially affecting how servers and security tools interpret them.
The source does not elaborate on specific security implications, but the change is notable for anyone involved in web protocol analysis or security monitoring.
