CVE-2026-49211

Symfony UX is a JavaScript ecosystem for Symfony. From 2.2.0 until 2.36.0 and 3.1.0, Symfony\UX\Autocomplete\Doctrine\EntitySearchUtil::addSearchClause() builds the LIKE expression used by the autocomplete endpoint by wrapping the client-supplied query in %...% without escaping SQL LIKE wildcards (%, _, \), allowing unauthenticated users to turn the public BaseEntityAutocompleteType endpoint into a broad matcher or blind boolean oracle against every column in default searchable_fields. This issue is fixed in versions 2.36.0 and 3.1.0.

Summary		(es) Symfony UX es un ecosistema JavaScript para Symfony. Desde 2.2.0 hasta 2.36.0 y 3.1.0, Symfony\UX\Autocomplete\Doctrine\EntitySearchUtil::addSearchClause() construye la expresión LIKE utilizada por el endpoint de autocompletado al envolver la consulta proporcionada por el cliente en %...% sin escapar los comodines SQL LIKE (%, _, \), permitiendo a usuarios no autenticados convertir el endpoint público BaseEntityAutocompleteType en un emparejador amplio o un oráculo booleano ciego contra cada columna en los “searchable_fields” predeterminados. Este problema se corrige en las versiones 2.36.0 y 3.1.0.
