CVE-2026-53826Network attack vector

Host workspace disclosure via sandboxed session spawning

Published Jun 12, 2026 · Updated Jun 12, 2026

Information disclosure in OpenClaw before 2026.4.26 allows remote authenticated users to reveal the host workspace path to child models. Sandboxed session spawning forwards the parent’s real host workspace path into the child session prompt instead of preserving the sandbox boundary. The feature must be enabled and reachable from a sandboxed parent; exposure is limited to host workspace location or related memory context.
