DescriptionCVE.org

OpenClaw before 2026.3.23 contains an insufficient access control vulnerability in the Gateway agent /reset endpoint that allows callers with operator.write permission to reset admin sessions. Attackers with operator.write privileges can invoke /reset or /new messages with an explicit sessionKey to bypass operator.admin requirements and reset arbitrary sessions.

AnalysisAI

Insufficient access control in OpenClaw Gateway agent allows authenticated attackers with operator.write permission to reset admin sessions without operator.admin authorization. By invoking /reset or /new endpoints with explicit sessionKey parameters, attackers bypass privilege requirements and terminate arbitrary administrative sessions, achieving high-impact session hijacking. Affects OpenClaw versions prior to 2026.3.23. No public exploit identified at time of analysis.

Technical ContextAI

CWE-862 missing authorization vulnerability permits privilege escalation through endpoint parameter injection. Gateway agent fails to validate caller privileges against sessionKey ownership, allowing operator.write users to manipulate admin-level session lifecycle operations without operator.admin role enforcement.

RemediationAI

Vendor-released patch: upgrade to OpenClaw version 2026.3.23 or later. Apply upstream commits 630f1479c44f78484dfa21bb407cbe6f171dac87 and 50f6a2f136fed85b58548a38f7a3dbb98d2cd1a0 which enforce proper authorization checks on Gateway agent /reset and /new endpoints. Review and restrict operator.write role assignments to trusted users. Audit session logs for unauthorized /reset invocations prior to patching.
