This isn't a security problem

All you did was use Jenkins as intended! If you don't have rights to change the job, this fails. (I checked ).
I would have expected a bypass of creds...

Other than that all you have is a useful script to change a job programmatically. I like it and have modded it to inject a new static analysis tool into all my pipelines!!

can't exploit it

Hi, hello, I build the environment according to your file, but this error is reported every time the vulnerability is exploited. Attribute Error:'NoneType'object has no attribute'text'

I tried to debug your script and found that the definition / script value in the ET value was not found in the environment I built, so I would like to consult you about how to deal with it.
