CVE-2026-22181Network attack vector

Authenticated SSRF via environment proxy dispatcher

Published Mar 18, 2026 · Updated Mar 18, 2026

SSRF in OpenClaw before 2026.3.2 allows remote authenticated users to access internal targets through configured environment proxies. Strict web-tool paths validate a resolved destination, then select EnvHttpProxyAgent instead of the DNS-pinned dispatcher for the connection. Exploitation requires attacker-influenced web-tool URLs and proxy environment variables; access is limited to targets reachable from that proxy environment.
