CVE-2026-85180Public exploitNetwork attack vectorHinoki check available

Internal-resource access via unvalidated tensor redirects

Published Sep 3, 2026 · Updated Sep 3, 2026

SSRF in Ollama 0.30.0 through 0.33.2 allows remote attackers to access internal hosts through malicious tensor-layer model pulls. The x/transfer/download.go resolve function returns cross-host redirect URLs without restricting the destination to the original registry, so blob retries send GET requests to the redirected host. Exploitation requires an attacker-controlled registry serving a tensor-layer manifest and an unauthenticated API pull request; the server can reach internal services and cloud metadata endpoints.
