Description

Trigger.dev before 4.5.6 contains an improper authorization vulnerability that allows holders of lower-trust environment API keys to cancel other environments' deployments because DeploymentService.getDeployment scopes lookups by projectId only. Attackers with a dev, preview, or CI secret key can POST to the deployment cancel endpoint to cancel in-progress production deployments within the same project.
