CVE-2026-4880
CriticalSummary
Wtyczka Barcode Scanner dla WordPressa jest podatna na eskalację uprawnień z powodu niebezpiecznej autoryzacji opartej na tokenach we wszystkich wersjach do 1.11.0. Problem wynika z zaufania wtyczki do dostarczonego przez użytkownika identyfikatora użytkownika w tokenie, co umożliwia atakującym uzyskanie ważnych tokenów autoryzacyjnych.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do uzyskania pełnych uprawnień administratora, co stwarza poważne zagrożenie dla bezpieczeństwa systemu i danych organizacji.
Recommendation
Zaleca się aktualizację wtyczki do najnowszej wersji, aby usunąć tę podatność oraz wdrożenie dodatkowych środków zabezpieczających, takich jak ograniczenie dostępu do akcji związanych z metadanymi użytkowników.

Original NVD description (English source)
The Barcode Scanner (+Mobile App) – Inventory manager, Order fulfillment system, POS (Point of Sale) plugin for WordPress is vulnerable to privilege escalation via insecure token-based authentication in all versions up to, and including, 1.11.0. This is due to the plugin trusting a user-supplied Base64-encoded user ID in the token parameter to identify users, leaking valid authentication tokens through the 'barcodeScannerConfigs' action, and lacking meta-key restrictions on the 'setUserMeta' action. This makes it possible for unauthenticated attackers to escalate their privileges to that of an administrator by first spoofing the admin user ID to leak their authentication token, then using that token to update any user's 'wp_capabilities' meta to gain full administrative access.
