## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 14 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:** 2.66.2
- **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.

The suspicious signals are attributable to a browser form/assistant SDK and its explicit custom-component feature. Direct inspection found no concrete malicious behavior or install-time attack path.

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 confirmed malicious attack surface. Runtime networking implements Feathery form, authentication, and assistant features; custom code execution is an explicit configured custom-field capability in a sandboxed iframe.

- **Trigger:** Consumer renders Feathery forms or enables configured assistant/custom-field features.

- **Impact:** No unconsented install-time mutation, credential harvesting, or covert remote payload chain established.

- **Evidence paths:** package.json, cjs/index.js, dist/fthry\_index.74n2xru4.js, dist/fthry\_AssistantChat.DsdEw0Ss.js, umd/CustomField.895d9a1d34e8e7b8b8d0.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T21:45:49.243Z

### AI review details

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

- **Mechanism:** Package-aligned browser SDK requests and user-configured iframe component execution.

- **Rationale:** The suspicious signals are attributable to a browser form/assistant SDK and its explicit custom-component feature. Direct inspection found no concrete malicious behavior or install-time attack path.

- **Files touched:** package.json, cjs/index.js, dist/index.js, dist/fthry\_index.74n2xru4.js, dist/fthry\_AssistantChat.DsdEw0Ss.js, umd/CustomField.895d9a1d34e8e7b8b8d0.js

- **Network endpoints:** https://api-static-2.feathery.io/api/, https://cdn.feathery.io/api/, https://m1.openfpcdn.io/fingerprintjs/, https://www.google.com/generate\_204

### Review decision

- **Verdict:** Clean

- **Confidence:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** \`umd/CustomField.895d9a1d34e8e7b8b8d0.js\` compiles and imports configured custom-component code in a sandboxed iframe., \`dist/fthry\_AssistantChat.DsdEw0Ss.js\` uploads user-selected assistant attachments and document-index content to its configured API.

- **Evidence against:** \`package.json\` has only \`prepare: husky\` and \`prepublishOnly: yarn build\`; no install/preinstall/postinstall hook., \`cjs/index.js\` is a normal library entrypoint with no install-time execution., \`dist/fthry\_index.74n2xru4.js\` routes SDK requests to declared Feathery API/CDN endpoints and attaches its session cookie only to those requests., No child-process, filesystem harvesting, persistence, destructive action, or covert exfiltration path was found in inspected runtime files., The high-entropy \`.woff2\` is a bundled font asset, not executable payload code.

## Affected versions and remediation
