CVE-2026-46629

Twig is a template language for PHP. Prior to 3.26.0, twig/intl-extra memoises IntlDateFormatter and NumberFormatter instances in arrays keyed by template-controlled filter arguments such as locale, pattern, and attrs, allowing a template to allocate many ICU formatter objects that remain pinned for the lifetime of the Twig\Environment. This issue is fixed in version 3.26.0.

Summary		(es) Twig es un lenguaje de plantillas para PHP. Antes de la versión 3.26.0, twig/intl-extra memoriza instancias de IntlDateFormatter y NumberFormatter en arrays indexados por argumentos de filtro controlados por la plantilla, como la configuración regional, el patrón y los atributos, permitiendo que una plantilla asigne muchos objetos formateadores ICU que permanecen anclados durante la vida útil del Twig\Environment. Este problema está solucionado en la versión 3.26.0.
