- Summary
- Firewall configured with unanimous strategy was not actually unanimous in Symfony
- Details
-
Description
On Symfony before 4.4.0, when a
Firewallchecks an access control rule (using the unanimous strategy), it iterates over all rule attributes and grant access only if all calls to theaccessDecisionManagerdecide to grant access.As of Symfony 4.4.0, a bug was introduced that prevents the check of attributes as soon as
accessDecisionManagerdecide to grant access on one attribute.Resolution
The
accessDecisionManageris now called with all attributes at once, allowing the unanimous strategy being applied on each attribute.The patch for this issue is available here for the 4.4 branch.
Credits
I would like to thank Antonio J. García Lagar for reporting & Robin Chalas for fixing the issue.
