CVE-2026-65699 (GCVE-0-2026-65699)

Vulnerability from cvelistv5 – Published: 2026-07-23 16:59 – Updated: 2026-07-23 18:17 X_Open Source Unsupported When Assigned

Title

AgentGPT 1.0.0 Authorization Bypass via Agent Task Creation

Summary

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.
