Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 18 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Persistence - **Selected version:** 5.5.5 - **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The automatic storage of reusable session credentials warrants a warning, but inspected source does not establish malicious behavior. Network and remote-control paths are user-configured or package-aligned. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-08-30T01:41:22.440Z - **Finished:** 2026-08-30T01:42:26.503Z - **Download time:** 508 ms - **Static scan time:** 3763 ms - **AI review time:** 59791 ms - **Total time:** 64063 ms 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:** A normal successful login automatically saves Facebook session state and cookie material in a local SQLite database. No automatic network exfiltration or install-time execution was confirmed. - **Trigger:** Application import creates the database directory; a successful login stores session data. - **Impact:** Other local processes or users able to read the project database could reuse the saved session. - **Evidence paths:** module/loginHelper.js, src/database/models/index.js, module/config.js, src/remote/remoteClient.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-30T01:42:26.503Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic local persistence of reusable session credentials. - **Rationale:** The automatic storage of reusable session credentials warrants a warning, but inspected source does not establish malicious behavior. Network and remote-control paths are user-configured or package-aligned. - **Files touched:** Fca\_Database, Fca\_Database/database.sqlite ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** Successful logins automatically store the session app state and cookie header in SQLite., The database is created under the consumer project's working directory., This persists reusable Facebook session material without a separate user command. - **Evidence against:** package.json has no install lifecycle scripts or self-dependency., The remote WebSocket feature is disabled by default and requires a configured URL., The external credential-login endpoint has no default host and refuses to run unless configured., No source evidence of child-process execution, secret exfiltration, or remote payload execution was found. ## Affected versions and remediation This report applies to fca-nx@5.5.5. - Review the evidence and your use of fca-nx@5.5.5 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
