## Affected

- OpenClaw: fixed in 2026.5.18
- openclaw (npm): fixed in 2026.5.18

## Description

OpenClaw before 2026.5.18 contains a code execution vulnerability where marketplace runtime extension metadata can redirect loading toward unscanned package payloads. Attackers with trusted operator access can manipulate extension metadata to load plugin code outside reviewed package entry points, bypassing security scanning.

## What to do

- Check your stack: if you ship or depend on OpenClaw, openclaw, upgrade to a fixed version (2026.5.18) per the references below.
