DisallowedModelAdminLookup raised when filtering on a ForeignKey not listed in list_filters

[Maxime Lorant]

Since Django 5.0.1, the exception DisallowedModelAdminLookup is raised when I'm trying to filter a list in the Django admin with a foreign key attribute not listed in list_filters. It looks like a regression from #35020, but I'm not exactly sure at 100 %. The exception is not raised when I'm filtering against a foreign key attribute listed in list_filters neither for a standard CharField not listed. Using the following simple example, on a fresh new Django project:

# models.py
class Client(models.Model):
    name = models.CharField("name", max_length=100)

class Invoice(models.Model):
    client = models.ForeignKey(Client, models.CASCADE, null=False)
    number = models.CharField("number", max_length=100)

# admin.py
@admin.register(models.Invoice)
class InvoiceAdmin(admin.ModelAdmin):
    pass   # note that no list_filters defined 

The URL /admin/core/invoice/?client=1 in local:

• returns a 200, with proper results in Django 4.2.9
• returns a 200, with proper results in Django 5.0.0
• returns a 500, from the exception below in Django 5.0.1

The exception raised in Django 5.0.1:

django.contrib.admin.exceptions.DisallowedModelAdminLookup: Filtering by client not allowed

The URL /admin/core/invoice/?number=ABC works in the three versions with the same behaviour each time (make an exact match on the charfield)
