• CVE-2026-53814: 0.28% estimated exploitation activity in the next 30 days; percentile 20.68 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary OpenClaw hook ingress can start automated agent runs using a configured hook token. In affected releases, a hook-triggered run could select a bundled CLI backend that received owner-scoped MCP loopback authority instead of a scope appropriate for hook ingress. This issue affects the boundary between hook-token automation and owner-only MCP tools. It does not affect deployments with hooks disabled. Affected configurations This affects deployments where hooks are enabled, /hooks/agent is reachable with a valid hook token, and a bundled CLI backend can be selected for the hook-triggered run. Impact A caller with the hook token could cause the spawned CLI runtime to see or call MCP tools that should have been owner-only. The practical impact depends on which MCP tools are available; the reported proof used persistent cron state as a representative owner-only action. Patched Versions The first stable patched version is 2026.5.20. Fixed in the 2026.5.20 stable release. Mitigations…

# Patch Next advisory brief: CVE-2026-53814

Advisory: OpenClaw: Hook-triggered CLI runs could receive owner MCP tool authority
IDs: CVE-2026-53814, GHSA-6fvr-66p3-3qj4
Record: https://patchnext.com/advisories/cve-2026-53814 (revision 3, source checked 26 Oct 2026, 12:56 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: openclaw 2026.5.20. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm openclaw: affected < 2026.5.20; fixed in 2026.5.20

## Suggested inspection (read-only)
- `npm ls openclaw --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on openclaw.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
