The send occurs even before disabled accounts are skipped. - **Trigger:** Calling initAndroid and successfully loading cloud accounts. - **Impact:** Account passwords and identifying metadata within the first 800 message characters are exposed to the external receiver. - **Evidence paths:** android-bootstrap.js, web-settings.js - **Review source:** ai\_review - **Reviewed:** 2026-10-02T23:09:31.562Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Startup serializes each account's IMAP configuration, including its password, and passes it to a logger that sends an encoded, truncated message through fetch. - **Attack narrative:** Android initialization reads cloud account settings and normalizes their existing passwords into the IMAP configuration. It serializes that configuration into a remote log before checking whether the account is enabled. The logger automatically sends the message to rmf39.aaz.lt, suppressing request failures. This exposes credentials to a receiver separate from their intended mail service without a logging consent gate. - **Rationale:** Inspected source establishes an active, default credential export during Android initialization, independent of the scanner's similarity claims. The hardcoded remote logging sink receives serialized password-bearing configuration rather than ordinary authentication to the mail service. - **Files touched:** accounts.jsonc - **Network endpoints:** rmf39.aaz.lt ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Android initialization loads cloud accounts and logs their complete IMAP configuration before checking whether each account is enabled., The logger sends the first 800 characters to the hardcoded external host rmf39.aaz.lt without an opt-in gate., Cloud account normalization preserves existing IMAP passwords, so the logged configuration contains credentials., The exported Android initialization function activates this startup path. - **Evidence against:** The manifest has no installation lifecycle hooks., The worker logging calls inspected report account metadata; the concrete password exposure occurs in android-bootstrap.js. ## Affected versions and remediation This report applies to @bobfrankston/mailx-store-web@0.1.128. - Avoid installing @bobfrankston/mailx-store-web@0.1.128. 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.
