CVE-2026-92780: KnowStreaming 3.4.1 lets any logged‑in user create admin accounts
CVE-2026-92780 · published 23 days ago
Summary
Versions of KnowStreaming up to 3.4.1 do not check a user's role when using its REST interface, so any person who can log in can call functions that add or promote accounts to administrators. This can give attackers full control over the system. Apply the latest software update that adds proper role checks, and review existing accounts for unexpected administrator privileges.

Original advisory text
KnowStreaming through 3.4.1 Missing Authorization on the REST API
KnowStreaming through 3.4.1 fails to enforce role-based access control on REST API endpoints, allowing any authenticated user to access protected functionality. Attackers can call identity-management endpoints to create administrator accounts or grant themselves administrative privileges without proper authorization.
