## Verdict summary
**Blocked & quarantined** — Unrequested provider usage can incur cost. The feature also processes session evidence for its evolution task.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Malware
- **Selected version:** 0.2.1
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

Evolution defaults to enabled and automatically calls the configured model after its usage thresholds are reached, consuming provider quota without a per-run request. The source documents the feature and its controls, but the automatic spending matches the stated malicious behavior rule.

## Security analysis

### Published attack-surface review

- **Summary:** Default-on background evolution can make additional model calls that consume the user's provider quota without a per-run request.

- **Trigger:** After session operations settle, automatic evolution is evaluated; eligible work starts once the token, invocation, and cooldown thresholds are met.

- **Impact:** Unrequested provider usage can incur cost. The feature also processes session evidence for its evolution task.

- **Evidence paths:** dist/core/settings-manager.js, dist/core/agent-session.js, dist/main.js, dist/core/evolution-runtime.js, dist/vendor/evolution/token-estimator.js, docs/settings.md

- **Review source:** ai\_review

- **Reviewed:** 2026-11-05T08:28:23.737Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** The CLI attaches the evolution coordinator to the session lifecycle. It sends accumulated invocation evidence through the current model runtime for background evolution.

- **Attack narrative:** With evolution enabled by default, settled session operations trigger automatic eligibility checks. After enough accumulated usage, the package calls the current model provider to process invocation evidence, consuming provider quota without a separate request for each run. The feature is documented and can be disabled, but the default still permits this automatic spending.

- **Rationale:** Evolution defaults to enabled and automatically calls the configured model after its usage thresholds are reached, consuming provider quota without a per-run request. The source documents the feature and its controls, but the automatic spending matches the stated malicious behavior rule.

- **Files touched:** agentDir/evolution-workspaces/\<workspace-id\>/traces/, agentDir/evolution-workspaces/\<workspace-id\>/evolution/

### Review decision

- **Verdict:** Malicious

- **Confidence:** 89.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** Evolution is enabled by default when no setting is present., The CLI wires the evolution coordinator into the session lifecycle; settled operations can trigger automatic evolution work., The evolution executor uses the configured model runtime to make provider calls with evolution messages and tools., Automatic work becomes eligible after 400,000 reported tokens across at least three invocations, and the docs note those calls may consume provider quota.

- **Evidence against:** The package documents evolution as a feature and describes its thresholds, cooldown, and quota use., Users can disable future tracing and evolution work through the evolution setting., The manifest has no install lifecycle scripts.

## Affected versions and remediation

This report applies to @diffexai/diffex@0.2.1.

- Avoid installing @diffexai/diffex@0.2.1. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
