What is CVE-2026-77877?

Control Web Panel (CWP) prior to version 1.30 suffers from a vulnerability that permits unauthenticated access to critical API endpoints. This issue arises due to a lack of authentication checks in the loopback API service. As a result, attackers who can reach the API can execute root-privileged actions without needing valid credentials or access tokens. Affected endpoints include /v1/restoredatabase/, /generaluser/, /last_access/, /valid_user/, /valid_token/, and /user_panel_dashboard/, thereby enabling unauthorized operations that can compromise security.

Affected Version(s)

Control Web Panel 0 < 1.30
