CVE-2023-41336: Prevent injection of invalid entity ids for "autocomplete" fields in symfony ux-autocomplete
First published: Mon Sep 11 2023(Updated: )
### 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](https://symfony.com/bundles/ux-autocomplete/current/index.html#usage-in-a-form-with-ajax). 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.
