CVE-2026-78369Network attack vector

Unauthorized crypto group creation via unguarded route

Published Aug 24, 2026 · Updated Aug 24, 2026

Missing authentication in RansomLook 2.0.0 and earlier allows remote attackers to create crypto group entries through its web interface. The /admin/crypto/group/new route in website/web/init.py invokes admin_crypto_group_new without flask_login.login_required, so GET and POST requests reach the administrative handler without a session. Network access to the web interface is sufficient to submit unauthorized group data, altering administrator-managed records and downstream data integrity.
