Official description

Trigger.dev before 4.5.10 contains a server-side request forgery vulnerability that allows authenticated project members to bypass webhook SSRF protections by targeting the non-global 198.18.0.0/15 benchmarking range. Attackers can configure alert-channel webhooks pointing at internally routed services in this range, which isUnsafeIPv4 omits, to perform blind internal probing and limited state-changing POST requests.
