CVE-2026-100591: OpenClaw missing owner authorization check on Active Memory global toggles

CVE-2026-100591 · Severity: medium · CVSS 6.3 · Published 2026-09-26

OpenClaw is an npm-distributed agent gateway that manages conversation memory for AI applications. An authorized non-owner user could exploit a missing authorization check to persistently enable or disable the gateway's Active Memory feature, either disrupting memory recall for future conversations or re-enabling memory where the owner intended it disabled. This affects confidentiality and availability of stored conversation data depending on what was previously recorded.

Technical details

The vulnerability is a missing authorization check (CWE-862) in Active Memory global toggle mutations. An authenticated external-channel sender without owner privileges can invoke persistent on/off mutations because the code omits owner verification. The attack requires network access and valid authentication credentials but no user interaction. Session-level controls and read-only operations are unaffected. The fix is available in version 2026.7.1.
