Official description

Trigger.dev before 4.5.2 contains a blind server-side request forgery vulnerability that allows authenticated project members to make the server send requests by setting unvalidated alert-channel webhook URLs. Attackers can create alert channels pointing to loopback, internal, or cloud metadata addresses, then trigger alerts to probe internal service reachability and send signed POST requests.
