symfony/ux-autocomplete fixed: 2.11.2 
Upgrade symfony/ux-autocomplete to 2.11.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for symfony/ux-autocomplete

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-41336, inspect your project dependencies for Symfony/ux autocomplete:

inspect dependencies for symfony/ux-autocomplete

Analyze the terminal output to locate any version of Symfony/ux autocomplete in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.11.2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Symfony/ux autocomplete, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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.
