    Summary: Improper token validation leading to code execution in Teleport

    Details: Teleport 9.3.6 is vulnerable to Command injection leading to Remote Code Execution. An attacker can craft a malicious ssh agent installation link by URL encoding a bash escape with carriage return line feed. 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.
