Hi - Thanks for reaching out and sharing the PoC code. We will need some time to set this up and test it. What OS did you use to test it? Did you use any containers?

Thanks for the update

thank you for your reply, my OS info:

OS: linux mint 20.3 (Una)   
unused container

$ cat /etc/debian_version
bullseye/sid

$ uname -a

Today, I tested with the container again and found that this problem only occurs when the request is made on the local network!
