Description

Trigger.dev versions before 4.5.2 fail to validate environment membership during run replay operations, allowing authenticated attackers to inject task runs into arbitrary environments. Attackers can replay their own runs into other organizations' or projects' environments to consume victim resources and pollute run history.
