GHSA-qh2f-99mv-mrcf: OpenClaw: Bundle MCP loopback could miss its exec denylist on session spawn

July 2, 2026

Bundle MCP loopback could miss its exec denylist on session spawn. In affected versions, a caller that can reach the affected bundled MCP session-spawn path could bypass the denylist that was intended for that loopback MCP entry point.

This advisory is scoped to the named feature and configuration. It does not change OpenClaw’s trusted-operator model: authenticated Gateway operators, installed plugins, and intentional local execution surfaces remain trusted unless a separate policy, approval, allowlist, sandbox, or auth boundary is crossed.
