DescriptionCVE.org

OpenClaw versions 2026.6.6 before 2026.6.9 contain an authorization bypass vulnerability in message mutation handling that allows lower-trust callers to perform actions requiring stronger authorization checks. Attackers can exploit misconfigured input paths to skip requester authorization and execute privileged operations when the affected feature is enabled and reachable.

AnalysisAI

Privilege escalation via authorization bypass in OpenClaw 2026.6.6 through 2026.6.8 allows a low-privileged, authenticated caller to invoke message-mutation operations that should require stronger authorization, letting them execute privileged actions. The flaw is a missing authorization check (CWE-862) on mutation input paths and requires the affected feature to be enabled and reachable. …

Vulnerability AssessmentAI

Exploitation Exploitation requires a low-privilege authenticated account (CVSS PR:L) able to send message-mutation requests over the network (AV:N), and requires the affected mutation feature to be enabled and reachable in the deployment. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The supplied CVSS 4.0 score is 7.1 (High) with vector AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:L. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker holding a low-privilege authenticated account on an OpenClaw instance sends a crafted message-mutation request through an input path that skips the requester authorization check. Because the mutation handler does not re-verify authorization for the privileged operation, the action executes with elevated effect, letting the attacker alter data or perform operations reserved for higher-trust roles. …
Remediation Upgrade to OpenClaw 2026.6.9 or later, the first release outside the affected 2026.6.6-2026.6.8 range and, per the version boundary, the fixed build; consult https://github.com/openclaw/openclaw/security/advisories/GHSA-v7hx-r36p-f68m for the authoritative patched version. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, identify all OpenClaw 2026.6.6-2026.6.8 deployments in your environment and verify whether the message-mutation feature is enabled on each system. …
