NVD description
OpenClaw versions prior to 2026.3.2 contain a DNS pinning bypass vulnerability in strict URL fetch paths that allows attackers to circumvent SSRF guards when environment proxy variables are configured. When HTTP_PROXY, HTTPS_PROXY, or ALL_PROXY environment variables are present, attacker-influenced URLs can be routed through proxy behavior instead of pinned-destination routing, enabling access to internal targets reachable from the proxy environment.
What to do
- Upgrade OpenClaw to
2026.3.2or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
