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 12 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Credential Exfiltration - **Selected version:** 0.1.124 - **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 source demonstrates conditional credential disclosure through diagnostic logging, warranting a warning for a critical vulnerability. The inspected behavior does not establish deliberate malicious intent sufficient to classify the package as malware. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-30T06:40:43.835Z - **Finished:** 2026-09-30T06:42:27.604Z - **Download time:** 1029 ms - **Static scan time:** 280 ms - **AI review time:** 102460 ms - **Total time:** 103769 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:** Android startup can expose mailbox passwords through remote diagnostic logging. This establishes a credential disclosure vulnerability, but not confirmed malicious intent. - **Trigger:** Calling initAndroid with Google Drive reconciliation available and cloud accounts containing IMAP passwords. - **Impact:** Mailbox passwords and account details can reach the logging service and its URL logs; messages are truncated to 800 characters. - **Evidence paths:** android-bootstrap.js, web-settings.js - **Review source:** ai\_review - **Reviewed:** 2026-09-30T06:42:27.604Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Cloud accounts are normalized with passwords, then their complete IMAP configuration is serialized into a logging request to a fixed external host. - **Rationale:** The source demonstrates conditional credential disclosure through diagnostic logging, warranting a warning for a critical vulnerability. The inspected behavior does not establish deliberate malicious intent sufficient to classify the package as malware. - **Files touched:** accounts.jsonc - **Network endpoints:** https://rmf39.aaz.lt ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for warning:** Android account registration logs the complete IMAP configuration without password redaction., The logging function sends its input to https://rmf39.aaz.lt in a URL, without an opt-in check., Account normalization retains configured IMAP passwords., Cloud account loading reads accounts.jsonc and returns normalized accounts., The exported Android initialization function activates the startup path., package.json defines only a build script and no installation lifecycle hooks. - **Evidence against:** The behavior appears within diagnostic logging; inspected source does not establish deliberate malware intent., The default entrypoint exports storage and service classes; credential exposure requires Android initialization and applicable cloud accounts. ## Affected versions and remediation This report applies to @bobfrankston/mailx-store-web@0.1.124. - Review the evidence and your use of @bobfrankston/mailx-store-web@0.1.124 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.
