This change is superseded by #2413. This was done to ensure that commits are signed. Orignal contribution history has been preserved. Hence closing this PR now. |
no it hasn't. I don't know who "Simen A. W. Olsen [email protected]" is but it isn't me and my commit here doesn't reference that name or email address at all. Was it ai generated or something? |

Hi @MegaManSec I sincerely apologize for this attribution error. Can confirm that an AI workflow was used to created the rebased commit, which got confused with OP details. Thank you for calling this out, we'll make sure this doesn't happen again. |
Credit Joshua Rogers (@MegaManSec) as the original author who discovered and fixed the OAuth parameter injection vulnerability in PR #2381. This corrects an attribution error in PR #2413 where the commit message incorrectly credited a different person.

Thank you. For the record, I also did see this the now-deleted ai generated response with the "you're absolutely right" slop which ChatGPT likes to make. 
It's not obvious why this PR wasn't merged as-is: the commit was signed off, and now the git history has removed my authorship from my code -- which is very likely a copyright infringement. |
|
Yeah, i had to manually stop it and delete the ai-generated comment. |
|
I would appreciate force-pushing a fix for the commit to properly include my information in the commit. |
|
Also: if I report this via bugcrowd am I going to have to go through the typical waste of time to satisfy their triagers (which I'm already wasting my time with the other issue which has already been fixed)? |
