AgentGPT through 1.0.0 contains an authorization bypass through user-controlled key vulnerability that allows authenticated users to attach tasks to another user's agent run by supplying a target run id in the request body without ownership verification. The AgentCRUD.create task and validate task count functions look up the target AgentRun using the client-supplied run id without confirming the run belongs to the requesting user, enabling an attacker who obtains a valid run id to corrupt task history, exhaust the per-run loop budget, and drive LLM costs against the victim's run.
