Auth bypass in Openclaw
CVE-2026-100591
OpenClaw is an npm-distributed agent gateway. In versions before 2026.7.1, the global Active Memory toggle mutations could omit owner checks. An authorized non-owner external-channel sender could therefore persistently enable or disable Active Memory for the Gateway, disabling memory recall for future sessions or re-enabling global recall where the owner expected it to remain disabled. The issue is limited to persistent global on/off mutations; session-level controls and read-only status remain governed by existing command policy. The issue is fixed in version 2026.7.1. (Suggested title: "OpenClaw before 2026.7.1 missing owner authorization check on Active Memory global toggles".)
