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.
