I would like to know how important it is to worry about faults from segurança to frameworks php (example: CakePHP, Laravel, Zend, Symfony, CodeIgniter, etc.)
Is it possible for a% to have flaws in its own library that would ultimately condemn the security of the application itself?
If not, would it be for framework ?
What gave me this doubt was that I hardly ever see anything about it, and it's kind of hard to think that something is not susceptible to failure.
