Current Behavior

I am facing the following issue: even though <cfzone> is assigned in jail.local it is not substituted at banning time. In fact if I set "echo " > /config/fail2ban/test.txt" as "banaction" I will get "" instead of the actual variable value. I feel maybe I am misunderstanding configuration settings, but I did a lot of trial/error.

This is my jail.local (snippet)

[DEFAULT]
cftoken = xyz....
cfzone = fd4ec1...
# Prevents banning LAN subnets
ignoreip = 10.0.0.0/8
           192.168.0.0/16
           172.16.0.0/12

...

Expected Behavior

No response

Steps To Reproduce

• Create a file action.d/cloudflare-token.local with toy example of actionban (in my case echo "<cfzone>" > /config/fail2ban/test.txt
• Set variable cfzone = ... in the jail.local
• trigger the ban action
• check the file
