NVD Description

Note: Versions mentioned in the description apply only to the upstream openclaw package and not the openclaw package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

OpenClaw before 2026.5.12 contains an exec denylist bypass vulnerability in the bundle MCP loopback session-spawn path that allows authenticated callers to bypass intended command restrictions. Attackers can reach the affected bundled MCP session-spawn path to start sessions with broader command reach than intended.
