The serialized IMAP configuration can contain a password. - **Trigger:** Calling the Android bootstrap with cloud accounts available. - **Impact:** An external host can receive email addresses, mail server details, and IMAP passwords. - **Evidence paths:** android-bootstrap.ts, web-settings.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-11T01:36:22.666Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote logging of serialized IMAP account configuration. - **Attack narrative:** When the Android bootstrap loads cloud accounts, it passes a message containing JSON.stringify(account.imap) to vlog. vlog places that message in a request URL sent to rmf39.aaz.lt. Account normalization assigns passwords into account.imap, so configured IMAP passwords are exposed to that unrelated remote endpoint whenever this initialization path runs. - **Rationale:** The package contains a concrete credential-exfiltration path, despite having no npm lifecycle hook. The logging endpoint is unrelated to the mail providers and receives serialized account credentials. - **Files touched:** android-bootstrap.ts - **Network endpoints:** https://rmf39.aaz.lt/logit/ ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The Android bootstrap sends verbose logs to a hard-coded third-party host., During account setup it serializes the complete IMAP configuration into those logs, which includes the account password. - **Evidence against:** package.json has no install lifecycle hook., The package also contains normal browser mail storage and Google API integration. ## Affected versions and remediation This report applies to @bobfrankston/mailx-store-web@0.1.113. - Avoid installing @bobfrankston/mailx-store-web@0.1.113. 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. ## Public findings ### 1.
