https://1.bp.blogspot.com/-nibhxYxL_dU/WWlvdqzVqgI/AAAAAAAAIPo/_mHlQijSxHEwrD5GdeVybD20bu3Iyyg_QCLcBGAs/s1600/h8.png
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.
