What is CVE-2026-100574?
CVE-2026-100574 is a high-severity server-side request forgery vulnerability in OpenClaw, published on 26 Sep 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
OpenClaw (npm package 'openclaw') before 2026.8.1 contains a server-side request forgery vulnerability in its trusted-host DNS checks. For fetches that use the trusted-host DNS recheck, a trusted hostname that resolves to an unspecified address (0.0.0.0 or ::) bypasses the SSRF destination validation. An attacker who can influence DNS for an allowed hostname can therefore cause a guarded fetch to reach a service bound only to loopback and disclose its response; the practical impact depends on the reachable service and the data it returns. Fixed in 2026.8.1.
Weakness: CWE-918
