Remote code execution via unvalidated model digest
Published May 31, 2024 · Updated Mar 27, 2025
Path traversal in Ollama before 0.1.34 allows remote attackers to overwrite arbitrary server files through a malicious model manifest. The server's GetBlobsPath function converts the manifest digest into a blobs-directory path without enforcing a sha256 prefix and exactly 64 hexadecimal digits. A network-exposed API and a pull from an attacker-controlled registry are required; Docker deployments running as root permit file corruption to become code execution.
