CVE-2026-62195
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedOpenClaw 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceOpenClaw versions 2026.5.20 through 2026.6.5 contain an authorization bypass in the MCP loopback feature where lower-privilege callers can execute owner-restricted tools by manipulating configured input paths to circumvent authorization checks, allowing unauthorized execution or persistence of privileged actions.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Determine installed OpenClaw versionRun 'openclaw --version' or check the package manifest/config file for the installed OpenClaw version numberAffected if version is >= 2026.5.20 and < 2026.6.6
-
Identify if MCP loopback feature is configuredExamine the OpenClaw configuration files (typically in /etc/openclaw/ or ~/.openclaw/) for any 'mcp', 'loopback', or similar MCP-related settingsAffected if MCP loopback feature is enabled in the configuration
-
Review configured input paths for MCP loopbackInspect the MCP loopback configuration entries to identify any input path settings that could be manipulated by lower-privilege callersAffected if MCP loopback is configured with user-controllable input path parameters
-
Check for unexpected privileged tool executionsReview OpenClaw audit logs or execution history for tool invocations that occurred via the MCP loopback interface from lower-privilege sessionsAffected if privileged tools were executed through MCP loopback by non-owner callers
You are affected if OpenClaw version is between 2026.5.20 and 2026.6.5 inclusive AND the MCP loopback feature is enabled with configurable input paths that could be manipulated by lower-privilege users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2026.6.6
Update OpenClaw to version 2026.6.6 or later which contains the fix for the authorization bypass in the MCP loopback feature.
2026.6.6
- 1. Identify the current installed version of OpenClaw by checking the application or configuration files
- 2. Stop any running OpenClaw services or processes
- 3. Upgrade OpenClaw to version 2026.6.6 or later using the package manager or build system used in your deployment (e.g., pip install openclaw==2026.6.6, docker pull openclaw:2026.6.6, or compile from source at the 2026.6.6 tag)
- 4. Verify the upgrade was successful by checking the installed version matches 2026.6.6 or later
- 5. Restart OpenClaw services
- 6. Test that the MCP loopback feature now correctly enforces authorization checks for lower-trust callers
