JQL Check if label is the same as in linked issue

[Leandra]

Hey Everyone!
I want to filter my issues for incorrect labels in tests.

The test are supposed to have the same label as the issue they are testing and linked with. 
So I need to get the issue they are linked with, get its label and then compare it to my original issues label. 
Is there a way to do it in JQL? Because I'm struggling to actually get the labels and compare them.

Thanks in advance!

You cannot achieve it by built in queries, you need a third party plugin like scriptrunner or JQL Search Extensions for Jira & reports 

Example

following will get all issues where your curernt issue lable=abc and linked issues label=abc

issue in linkedBy(label=abc") and label=abc

I was afraid this would be the case. 
Thanks for your answer!
