Persistent service interruption via unbounded workflow downloads
Published Jun 18, 2026 · Updated Jun 18, 2026
Uncontrolled resource consumption in AutoGPT before 0.6.63 allows remote attackers to exhaust server disk space through crafted agent workflows. The StepThroughItemsBlock imposes no loop bound while FileStoreBlock writes each downloaded item without a disk-space quota, and delayed cleanup can retain the files indefinitely. An attacker must submit an agent workflow containing repeated media downloads; exhausting the working directory persistently interrupts the server service.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
