CVE-2026-51856 (GCVE-0-2026-51856)

Vulnerability from cvelistv5 – Published: 2026-09-30 00:00 – Updated: 2026-10-01 16:09
VLAI
Summary
In agentscope 1.0.18, 1.0.19, and 1.0.19 when the RealtimeAgent session exposes execute_python_code as an available tool, a remote WebSocket user can prompt the agent to call that tool and run Python code in the service environment. In the validated path, RealtimeAgent._acting forwards the model-produced tool call to Toolkit.call_tool_function, which invokes execute_python_code without an additional approval or isolation boundary on that path.
