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.
