## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 13 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 5.5.0
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

Direct inspection resolved the scanner’s credential and evaluation hints: license claims are reduced to status and expiry analytics, GitHub credentials go to GitHub, and the flagged UI code renders search results and examples. The package has no install hook, and the inspected telemetry is tied to CLI use with opt-out controls or explicit cloud analytics configuration.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 90.0%

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** No attack surface was identified in the inspected source. The CLI sends package analytics, with opt-out controls, and separately gates cloud inventory reporting on configured analytics settings.

- **Trigger:** Running EventCatalog CLI commands that build, start, or develop a catalog; cloud inventory reporting also requires enabled configuration and credentials.

- **Impact:** The inspected behavior supports product analytics and catalog rendering; it does not establish credential theft or another attack.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-20T16:38:45.070Z

### AI review details

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

- **Mechanism:** The CLI sends event metadata and a short catalog content hash to its analytics endpoint. Cloud inventory uses a configured endpoint and write key; GitHub tokens are attached to GitHub requests.

- **Rationale:** Direct inspection resolved the scanner’s credential and evaluation hints: license claims are reduced to status and expiry analytics, GitHub credentials go to GitHub, and the flagged UI code renders search results and examples. The package has no install hook, and the inspected telemetry is tied to CLI use with opt-out controls or explicit cloud analytics configuration.

- **Files touched:** package.json, dist/eventcatalog.cjs, dist/eventcatalog.js, dist/chunk-YRZK7HKX.js, eventcatalog/src/components/Search/SearchModal.tsx, eventcatalog/src/components/SchemaExplorer/ExamplesViewer.tsx, eventcatalog/src/features/mcp/mcp-server.ts, eventcatalog/src/features/storage/database.ts

- **Network endpoints:** https://queue.simpleanalyticscdn.com/events, https://api.ecingest.dev/v1/analytics/ingest, https://api.github.com

### Review decision

- **Verdict:** Clean

- **Confidence:** 90.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The manifest exposes a CLI entry point and lists ordinary development and build scripts; it has no install lifecycle hook., The flagged runtime operations are CLI process handling and EventCatalog catalog setup., The flagged search and schema-viewer code handles UI components and displays examples; the inspected excerpts show no code evaluation., The inspected dependency snapshots expose AI SDK hooks and Astro markdown and MDX rendering behavior., CLI telemetry has explicit opt-out checks and sends EventCatalog event metadata to its analytics endpoint; cloud inventory reporting requires enabled analytics, a tracking ID, and a write key., The local license file is parsed for claims, while GitHub tokens are used in requests directed to GitHub; reported license analytics contain status and expiry fields.

## Affected versions and remediation

This report applies to @eventcatalog/core@5.5.0.

- Review the evidence and your use of @eventcatalog/core@5.5.0 before allowing it. Restrict the permissions described in this report.

```

### 3. Medium: Dynamic Require
- **Category:** Source
- **Confidence:** 75.0%
- **Path:** dist/chunk-754U4T7K.js
- **Public source:** [View source](<https://unpkg.com/@eventcatalog/core@5.5.0/dist/chunk-754U4T7K.js>)

Package source references dynamic require/import behavior.

Public source snippet (untrusted):

```javascript
L41: try {
L42: const importedGenerator = await import(plugin);
L43: const generator2 = getDefaultExport(importedGenerator);
```

### 4. Medium: Network

- **Public source:** [View source](<https://unpkg.com/@eventcatalog/core@5.5.0/dist/eventcatalog.cjs>)

Source appears to send environment or credential material to an external endpoint.

Public source snippet (untrusted):

```javascript
L30: var import_commander = require("commander");
L31: var import_node_child_process2 = require("child_process");
L32: var import_node_path22 = require("path");
L33: var import_node_http = __toESM(require("http"), 1);
L34: var import_fs = __toESM(require("fs"), 1);
...
L80: }`;
L81: (0, import_node_module.register)(`data:text/javascript,${encodeURIComponent(hook)}`);
L82: };
...
L84: try {
L85: const packageJson = JSON.parse(await (0, import_promises.readFile)(import_node_path.default.join(projectDirectory, "package.json"), "utf-8"));
L86: return packageJson?.type === "commonjs";
...
L290: }
```

### 8. High: Copied Package Dependency Bridge
- **Category:** Source
- **Confidence:** 83.0%
- **Path:** dist/chunk-YRZK7HKX.js
- **Public source:** [View source](<https://unpkg.com/@eventcatalog/core@5.5.0/dist/chunk-YRZK7HKX.js>)

Package metadata claims a different repository identity while copied source loads a runtime dependency bridge.

Public source snippet (untrusted):

```javascript
package = @eventcatalog/core; repositoryIdentity = eventcatalog; dependency = @eventcatalog/fitness
L32: try {
L33: const { discoverFitnessFiles } = await import("@eventcatalog/fitness");
L34: return discoverFitnessFiles(projectDir).files.length;

### 10. Low: Url Strings
- **Category:** Supply Chain
- **Confidence:** 65.0%

Package source contains URL literals.

### 11. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 100.0%

Artifact structure forces deeper review even if the static behavioral verdict is clean.

### 12. High: Semantic Analysis Limited
- **Category:** Scanner Coverage
- **Confidence:** 100.0%
- **Path:** eventcatalog/src/components/SchemaExplorer/ExamplesViewer.tsx\#virtual:normalized:round1
- **Public source:** [View source](<https://unpkg.com/@eventcatalog/core@5.5.0/eventcatalog/src/components/SchemaExplorer/ExamplesViewer.tsx%23virtual%3Anormalized%3Around1>)

A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review.

Public source snippet (untrusted):

```text
stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 3
```

### 13. Critical: Previous Version Dangerous Delta
- **Category:** Supply Chain
- **Confidence:** 93.0%
- **Path:** dist/eventcatalog.cjs
- **Public source:** [View source](<https://unpkg.com/@eventcatalog/core@5.5.0/dist/eventcatalog.cjs>)
