What is the ruling on obtaining paid programming courses for free from their website due to a vulnerability that allows it?

The presence of a vulnerability on a website does not permit attacking paid courses, as Allah Almighty says: ﴿O you who have believed, do not consume one another’s wealth unjustly but only [in lawful] trade by mutual consent.﴾ [An-Nisa: 29]. Wealth is forbidden unless given willingly by its owner. Intellectual property is among the protected rights, and it is not permissible to infringe upon it. This is what has been affirmed by the jurisprudential councils and the general body of contemporary scholars.
