CVE-2026-57443Public exploitNetwork attack vectorHinoki check available

Email digest disclosure via unauthenticated ops endpoint

Published Sep 25, 2026 · Updated Sep 25, 2026

Missing authentication in SCBE-AETHERMOORE 4.0.2 through 4.2.0 allows remote attackers to read operator email metadata via an ops API. The AetherBrowser check-email route starts email_reader.py without an access-control dependency and returns up to 2,000 characters of its stdout. Exposure requires a reachable API server and configured IMAP credentials; responses disclose senders, subjects, and body snippets without allowing mailbox changes.
