description

npm package trigger.dev versions before 4.5.2 allow an authenticated user to replay task runs in another organization and to trigger completion checks for its batches. This can execute work using the target environment's configured secrets, consume its resources, or alter task processing when the attacker can identify a target run or batch.

mitigation

Upgrade trigger.dev to version 4.5.2 or later. Until the upgrade is complete, restrict access to the affected replay and batch-completion endpoints to trusted users and networks.

fixed in 4.5.2
