DescriptionCVE.org

OpenClaw versions 2026.5.20 before 2026.6.6 contain an authorization bypass vulnerability in the MCP loopback feature that allows lower-trust callers to execute owner-only tools. Attackers can bypass authorization checks through configured input paths to execute or persist actions beyond their intended permissions.

AnalysisAI

Authorization bypass in OpenClaw 2026.5.20 through 2026.6.5 lets a low-privilege caller invoke owner-only tools through the MCP loopback feature, escalating beyond intended permissions to execute or persist privileged actions. The flaw stems from incorrect permission enforcement (CWE-732) on configured input paths reachable over the network. …

Vulnerability AssessmentAI

Exploitation Exploitation requires (1) network access to an OpenClaw instance running an affected version 2026.5.20-2026.6.5, (2) a low-privilege/low-trust foothold (CVSS PR:L - a valid but non-owner caller, integration, or session), and (3) the presence of the MCP loopback feature with configured input paths that forward requests into the loopback handler. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base score of 8.7 (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:L) indicates a network-reachable, low-complexity attack that nonetheless requires the attacker to already hold some low-privilege access (PR:L) - this is a privilege-escalation/authorization-bypass, not a fully unauthenticated compromise. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker holding a low-privilege OpenClaw account or a low-trust integration crafts a request to a configured input path that is forwarded into the MCP loopback handler. Because the handler does not re-check the caller's trust level, the request executes an owner-only tool, letting the attacker persist configuration or run privileged actions. …
Remediation Vendor-released patch: 2026.6.6 - upgrade OpenClaw to 2026.6.6 or later, which contains the fixed authorization enforcement per GHSA-52xj-c9p8-78cv (https://github.com/openclaw/openclaw/security/advisories/GHSA-52xj-c9p8-78cv). … Detailed patch versions, workarounds, and compensating controls in full report.
