Technical Analysis

Rating this as a high-value vulnerability for attackers. This does require auth to exploit, either via user credentials or a personal access token. This could either be done with stolen credentials or by creating an account if that is permitted on the target instance. Exploitation appears to be straightforward; initiate a repository import which contains the payload / RESP message and get a shell. The only caveat here is that the repository needs to be publicly available to the Gitlab instance.

The Hackerone report goes into more detail on how the RESP message actually gets executed. This one is important to patch.
