This vulnerability in Ollama up to version 0.18.1 involves improper handling of requests in the Model Pull API's server/download.go file, which can be exploited remotely to perform server-side request forgery. SSRF vulnerabilities allow attackers to induce the server to make unintended requests, potentially accessing internal resources or services. No official remediation or patch has been announced by the vendor, and no known exploits are reported in the wild.

Successful exploitation of this SSRF vulnerability could allow an attacker to make the Ollama server send crafted requests to internal or external systems, potentially leading to unauthorized access to internal services or data. The CVSS score of 5.3 indicates a medium impact, reflecting limited privileges required and low complexity of attack but with some impact on confidentiality, integrity, or availability.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vendor has not responded or released a fix, users should monitor official channels for updates. Until a patch is available, consider restricting network access to the affected API or implementing network-level controls to limit outbound requests from the server to trusted destinations only.
