Doc Text:
A flaw was found in Ollama. Improper input validation within the model name parsing logic allows a remote attacker to conduct a Server-Side Request Forgery (SSRF) attack through the pull API. By supplying a crafted model name, an attacker can coerce the server into sending unauthorized network requests to internal or restricted network endpoints, potentially exposing sensitive internal services.
