CVE-2026-59240Network attack vector

Authenticated notification deletion via unscoped object lookup

Published Jul 27, 2026 · Updated Jul 27, 2026

Authorization bypass in Roskus Prospero Flow CRM 1.0.0 through 5.5.0 allows remote authenticated users to delete others' notifications. DeleteNotificationController::delete() passes the sequential path identifier to Notification::findOrFail() and deletes the returned record without checking user_id or company_id ownership. Any authenticated account can enumerate identifiers across tenants, removing ticket alerts, task assignments, and other system-event notifications from their intended recipients.
