Description
Hydra is a Continuous Integration service for Nix based projects. It is possible to trigger evaluations in Hydra without any authentication. Depending on the size of evaluations, this can impact the availability of systems.

Users unable to upgrade should deny the /api/push route in a reverse proxy. This also breaks the "Evaluate jobset" button in the frontend.
