Description
Kimi Code (@moonshot-ai/kimi-code) before 0.27.0 implements FetchURL SSRF hardening as a static hostname and IP-literal denylist in assertSafeFetchTarget, without resolving DNS or re-validating hosts after HTTP redirects. An attacker who can influence a FetchURL call (for example via prompt injection) can supply a crafted public hostname that resolves to loopback or another internal address, or a public URL that redirects to such a target, and thereby reach internal network services that the denylist was intended to block. FetchURL is included in the default auto-approve tool set, so the call does not require interactive user confirmation in manual mode.

Remediation

Vendor Solution

Upgrade to Kimi Code 0.27.0 or later. The fix resolves hostnames via DNS and rejects addresses in loopback, RFC1918, link-local, CGNAT, and ULA ranges; follows redirects manually with per-hop revalidation; and pins connections to the validated resolved addresses to reduce DNS-rebinding (TOCTOU) races.
