Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
scbe-aethermoore versions 4.0.2 through 4.2.0 have an unauthenticated AetherBrowser API endpoint that returns operator email metadata. A remote attacker who can reach port 8100 can read senders, subjects and body snippets from configured ProtonMail or Gmail accounts. Upgrade to 4.2.1; until then, restrict network access to that port.
