Symfony version(s) affected

v6.3.0-BETA1

Description

#49331 allowed to escape [ and . from PropertyPath strings, but the test suite was incomplete, and mostly covers the objects syntax (like foo.bar) and not so much the array syntax (like [foo][bar]). The author (@alanpoulain) mentioned :

I tried to modify the regexp as little as possible and to handle (really) edge cases such as double escaping.

So maybe that was intentional ? Still, I don't think this bug can be considered as an edge-case...

How to reproduce

<?php
new PropertyPath('[foo \[bar]][baz \. biz]');

throws an Exception :

Symfony\Component\PropertyAccess\Exception\InvalidPropertyPathException^ {#2696
  #message: "Could not parse property path "[foo \[bar]][baz \. biz]". Unexpected token "]" at position 11."
  #code: 0
  #file: "./vendor/symfony/property-access/PropertyPath.php"
  #line: 129
  trace: {
    ./vendor/symfony/property-access/PropertyPath.php:129 { …}
    ./var/script.php:52 {
      › 
      › dd(new PropertyPath('[foo \[bar]][baz \. biz]'));
      › 
      arguments: {
        $propertyPath: "[foo \[bar]][baz \. biz]"
      }
    }
  }
}
