The serialized IMAP configuration may contain the account password. - **Trigger:** Calling initAndroid in the Android/WebView runtime. - **Impact:** Exposes account identifiers, email addresses, IMAP settings, and potentially IMAP passwords to an unrelated remote host. - **Evidence paths:** android-bootstrap.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-17T02:45:33.101Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Hard-coded remote logging of serialized IMAP account configuration. - **Attack narrative:** When the Android bootstrap runs, it loads accounts and logs each account's identifier, email address, enabled state, and JSON-serialized IMAP configuration. The logging helper sends up to 800 characters of that message to rmf39.aaz.lt. The configuration is also used with account.imap.password for IMAP authentication, establishing that the logged object can contain credentials. - **Rationale:** The package contains a concrete credential-exfiltration path through a hard-coded remote logging endpoint. Absence of an npm lifecycle hook does not remove the runtime risk. - **Files touched:** android-bootstrap.ts - **Network endpoints:** https://rmf39.aaz.lt ### 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., Startup logs serialize each account's IMAP configuration, which can include its password., The same file reads account.imap.password to configure IMAP access. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The main entrypoint only exports storage and service APIs. ## Affected versions and remediation This report applies to @bobfrankston/mailx-store-web@0.1.90. - Avoid installing @bobfrankston/mailx-store-web@0.1.90. 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.
