OpenClaw (npm package `openclaw`) before 2026.8.1 incorrectly enforces sender tool policies during session-memory filename generation. In affected versions, filename generation created an embedded helper that retained tools which the originating sender's policy had removed. When session-memory filename generation was enabled for an agent reachable by lower-trust senders, model-mediated instructions could cause the helper to invoke tools outside that sender's effective policy; the demonstrated impact was the creation of persistent scheduled work. Exploitability depends on the model acting on the injected instruction and on which tools the helper exposes. The issue is fixed in 2026.8.1; as a workaround, disable session-memory filename generation for agents reachable by lower-trust senders.
