Executive Summary

This vulnerability is a server-side request forgery (SSRF) in Ollama versions up to 0.34.1. It exists in the IsValid function of the types/model/name.go file within the Pull API component. An attacker can remotely manipulate the function to forge requests to internal systems.

Impact Analysis

The SSRF vulnerability allows remote attackers to send crafted requests to internal services, potentially accessing sensitive data or internal networks. This could lead to unauthorized information disclosure, internal system manipulation, or further network compromise.

Compliance Impact

This vulnerability may violate compliance requirements under GDPR and HIPAA by exposing personal or health data through unauthorized internal access. It undermines data protection principles and could lead to regulatory penalties.

Mitigation Strategies

Upgrade Ollama to version 0.34.2 or later to address the server-side request forgery vulnerability in the Pull API.
