GHSA-6xf3-5hp7-xqqg: Improper token validation leading to code execution in Teleport

Teleport 9.3.6 is vulnerable to Command injection leading to Remote Code Execution.

This url encoded payload can be used in place of a token and sent to a user in a social engineering attack. This is fully unauthenticated attack utilizing the trusted teleport server to deliver the payload.
