Official description

Trigger.dev before 4.5.2 contains a blind server-side request forgery vulnerability that allows authenticated tenants to make the webapp server send POST requests to internal hosts by setting an unvalidated webhook alert channel URL. Attackers can point the webhook at internal services or cloud metadata addresses and trigger alerts to scan internal hosts, send state-changing POSTs, or reach IMDSv1 via redirects.
