AI-suggested

A fix is available in OpenClaw version 2026.4.26. Until upgrading, avoid spawning child sessions from sensitive sandboxed workspaces. Additionally, restrict channel and tool allowlists, avoid sharing a single Gateway instance between mutually untrusted users, and disable the sandboxed session spawn feature when not required.

Description

OpenClaw versions prior to 2026.4.26 contain a vulnerability where spawning a child session from a sandboxed parent session could expose the real host workspace path to the child session prompt. This exposure may reveal sensitive workspace location or related memory context depending on the operator's configuration and trust boundaries. The issue does not affect the overall trusted-operator model but is scoped to the sandboxed session spawn feature. The vulnerability has moderate impact and no known exploits in the wild. Mitigation includes avoiding spawning child sessions from sensitive sandboxed workspaces until patched and applying configuration hardening such as narrow allowlists and disabling the feature if not needed.
