Description
Trigger.dev before 4.5.2 contains a server-side request forgery vulnerability in webhook alert channel delivery URLs that are fetched without validation or SSRF protection. Authenticated users with organization membership can create alert channels with URLs targeting internal services and metadata endpoints, allowing the server to issue POST requests to restricted resources.
