In symfony/security-http before versions 4.4.7 and 5.0.7, when a `Firewall` checks access control rule, it iterate overs each rule's attributes and stops as soon as the accessDecisionManager decides to grant access on the attribute, preventing the check of next attributes that should have been take into account in an unanimous strategy. The accessDecisionManager is now called with all attributes at once, allowing the unanimous strategy being applied on each attribute. This issue is patched in versions 4.4.7 and 5.0.7.

Affected: Packagist: symfony/security, Packagist: symfony/security-http, Packagist: symfony/symfony

Description -----------

On Symfony before 4.4.0, when a `Firewall` checks an access control rule (using the unanimous strategy), it iterates over all rule attributes and grant access only if *all* calls to the `accessDecisionManager` decide to grant access.

As of Symfony 4.4.0, a bug was introduced that prevents the check of attributes as soon as `accessDecisionManager` decide to grant access on one attribute.

Resolution ----------

The `accessDecisionManager` is now called with all attributes at once, allowing the unanimous strategy being applied on each attribute.

The patch for this issue is available [here](https://github.com/symfony/symfony/commit/c935e4a3fba6cc2ab463a6ca382858068d63cebf) for the 4.4 branch.
