It is recommended to update the plugin to version 4.16 or higher immediately.
Azərbaycanca: Newsletters WordPress plaqini 4.16 versiyasından əvvəlki versiyalarda API autentifikasiya açarını dəqiq müqayisə etmir. Bu zəiflik autentifikasiya olunmamış hücumçulara ‘type juggling’ vasitəsilə API-dən yan keçməyə və abunəçi məlumatlarını dəyişmək, e-poçt göndərmək kimi imtiyazlı əməliyyatlar aparmağa imkan verir. Plaqini dərhal 4.16 və ya daha yuxarı versiyaya yeniləmək tövsiyə olunur.
