Detailsinfo

A vulnerability classified as critical was found in OpenClaw up to 2026.3.1. Affected by this vulnerability is an unknown part of the component Environment Variable Handler. The manipulation with an unknown input leads to a server-side request forgery vulnerability. The CWE definition for the vulnerability is CWE-918.

As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.
