What is broken object level authorization?
Broken Object Level Authorization (BOLA) - allows attackers to access and manipulate other users' resources by being authenticated users.
Azərbaycanca: Pozulmuş obyekt səviyyəli avtorizasiya (BOLA) - hücumçulara autentifikasiya olunmuş istifadəçilərin digər istifadəçilərin resurslarına daxil olmaq və manipulyasiya etmək imkanı verir.
