CVE-2026-57443: SCBE-AETHERMOORE Unauthenticated AetherBrowser Ops API Exposes Operator Email Digests
The AetherBrowser API server (scripts/aetherbrowser/api_server.py) exposes the POST /api/ops/check-email endpoint without any authentication. Any remote attacker can call this endpoint and trigger execution of the email_reader.py subprocess, which connects to configured ProtonMail or Gmail accounts via IMAP and returns email metadata (sender, subject, body snippet) in the JSON response. The server binds to 0.0.0.0:8100 by default with CORS set to allow_origins=["*"], making it reachable from any network or browser origin. This constitutes a critical information-disclosure vulnerability.
