• CVE-2026-53810: 0.42% estimated exploitation activity in the next 30 days; percentile 36.30 (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 Marketplace runtime extension metadata could point at unscanned payloads. In affected versions, a package selected for installation by a trusted operator could redirect runtime loading toward hidden package content that was not scanned as expected. This advisory is scoped to the named feature and configuration. It does not change OpenClaw's trusted-operator model: authenticated Gateway operators, installed plugins, and intentional local execution surfaces remain trusted unless a separate policy, approval, allowlist, sandbox, or auth boundary is crossed. Impact When the affected feature is enabled and reachable, this could load plugin code outside the reviewed package entry points. Practical impact depends on the operator's configuration and whether lower-trust input can reach that path. Patched Versions The first stable patched version is 2026.5.18. Mitigations Install only trusted plugins and keep plugin allowlists explicit until patched. As general hardening, keep channel…

# Patch Next advisory brief: CVE-2026-53810

Advisory: OpenClaw's marketplace runtime extension metadata could point at unscanned payloads
IDs: CVE-2026-53810, GHSA-v6r2-jh58-xx6w
Record: https://patchnext.com/advisories/cve-2026-53810 (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 7.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: openclaw 2026.5.18. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm openclaw: affected < 2026.5.18; fixed in 2026.5.18

## 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.
