Description
OpenClaw versions prior to 2026.3.1 fail to enforce sandbox inheritance during cross-agent sessions_spawn operations, allowing sandboxed sessions to create child processes under unsandboxed agents. An attacker with a sandboxed session can exploit this to spawn child runtimes with sandbox.mode set to off, bypassing runtime confinement restrictions.
