NVD description
A flaw has been found in NightTrek Ollama-mcp up to 80cf2e17cfc144963a475b619093a2d13c13dbc9. This affects an unknown part of the file src/index.ts. This manipulation of the argument name/modelfile/source/destination causes command injection. The attack can only be executed locally. This product is using a rolling release to provide continious delivery. Therefore, no version details for affected nor updated releases are available. The project was informed of the problem early through an issue report but has not responded yet.
What to do
- NVD lists no fixed version yet: follow the vendor advisory below and keep Ollama off the public internet until a fix ships.
- Do not expose the component's API or UI to the internet without authentication in front of it.
