CVE-2023-41336

CVE-2023-41336: Prevent injection of invalid entity ids for "autocomplete" fields

Impact

Under certain circumstances, an attacker could successfully submit an entity id for an EntityType that is not part of the valid choices.

Affected applications are any that use:

A custom query_builder option to limit the valid results; AND
An EntityType with 'autocomplete' => true or a custom AsEntityAutocompleteField.

Under this circumstance, if an id is submitted, it is accepted even if the matching record would not be returned by the custom query built with query_builder.

Patches

The problem has been fixed in symfony/ux-autocomplete version 2.11.2.

Workarounds

Upgrade to version 2.11.2 or greater of symfony/ux-autocomplete or perform extra validation after submit to verify the selected option is valid.

Root Cause Analysis

The vulnerability stems from how submitted entity IDs were validated. The original implementation in AutocompleteEntityTypeSubscriber's preSubmit method constructed a new query_builder (via $repository->createQueryBuilder('o')) instead of using the potentially restricted query_builder provided via the form options. This allowed attackers to submit IDs that would not be returned by the application's intended query_builder. The patch fixes this by utilizing the existing query_builder from options (including its constraints) and properly applying WHERE conditions to it. The test case modifications in AutocompleteFormRenderingTest.php confirm that IDs excluded by query_builder logic are now rejected post-fix.
