Very proud of our security team for the responsive communication and ensuring the issue is made public https://gitlab.com/gitlab-org/gitlab-ce/issues/54189#note_12...
Credit where credit's due to HackerOne co-founder jobert, too. Seems he's made a decent living [0] out of making GitLab more secure.
On the flipside, as a GitLab user, I'm glad to see you guys are so generous with bounties to encourage more detailed (and fascinating) reports like these. :)
