@hashbrownai/ollama@0.8.0
Ollama provider for Hashbrown AI
AI Security Review
scanned 13d ago · by lpm-firewall-aiThe postinstall telemetry automatically sends installation context and may include identifying Git details, so it presents a privacy risk. Its default endpoint is package-aligned and the source shows no separate concrete attack, supporting a warning rather than a block.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
Installing the package runs its postinstall hook.
Impact
Installation and potentially personal Git details are reported to the publisher without an affirmative opt-in in the inspected path.
Mechanism
The collector gathers an installation event and sends it to the default Hashbrown endpoint; Git identity can be added outside CI, unless telemetry is disabled.
AI rationale
The postinstall telemetry automatically sends installation context and may include identifying Git details, so it presents a privacy risk. Its default endpoint is package-aligned and the source shows no separate concrete attack, supporting a warning rather than a block.

Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package manifest runs a postinstall hook, which activates the collector during installation.
- The collector gathers installation and consumer context, and can include Git display name and email outside CI.
- The collector sends the event to a fixed Hashbrown endpoint by default; only loopback endpoint overrides are accepted.
- The package exports an Ollama text streaming adapter as its runtime API.
Evidence against
- The telemetry is sent to the package publisher's Hashbrown endpoint, and users can disable collection with recognized opt-out variables.
- The collector is bounded by short timeouts and failures do not fail installation.
