CVE-2026-17534

5th percentile - higher than 5% of all known CVEs

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.

The organization risks that an attacker (e.g., via prompt injection) can access internal network services that should be unreachable, potentially leading to data leakage or further compromise.

Update @moonshot-ai/kimi-code to version 0.27.0 or later, which includes a fix for the FetchURL SSRF protection.
