Miggo AIRoot Cause Analysis

The vulnerability stems from incomplete association handling in criteria processing. The patched commit ad83d388 modifies SalesChannelRepository.php to add processing of ManyToManyAssociationField's toManyReferenceDefinition, indicating the original implementation lacked this crucial step. This omission allowed extensions with ManyToMany associations to bypass field-level access controls (ApiAware checks) when serializing responses, as the criteria protections weren't applied to both sides of the association.
