Descriptions

MH-WikiBot (an IRC Bot for interacting with the Miraheze API), had a bug that allowed any unprivileged user to access the steward commands on the IRC interface by impersonating the Nickname used by a privileged user as no check was made to see if they were logged in. The issue has been fixed in commit 23d9d5b0a59667a5d6816fdabb960b537a5f9ed1.

MH-WikiBot (un IRC Bot para interactuar con la API Miraheze), presenta un bug que permitía a cualquier usuario no privilegiado acceder a los comandos de administrador en la interfaz IRC al suplantar el Nickname usado por un usuario privilegiado, ya que no se realizó ninguna comprobación para ver si iniciaron sesión. El problema ha sido corregido en el commit 23d9d5b0a59667a5d6816fdabb960b537a5f9ed1.
