CVE-2026-114077

Trigger.dev before 4.5.6 contains an authorization bypass vulnerability in createDeploymentBackgroundWorkerV4 that resolves a WorkerDeployment by friendlyId alone, without environment, project, or organization scoping. Attackers holding only their own environment API key can POST to the deployment background-workers endpoint with a victim's deployment ID to re-point that in-progress deployment at a worker in the attacker's environment.
