CVE-2025-61766

Bucket is a MediaWiki extension to store and retrieve structured data on articles. Prior to version 1.0.0, infinite recursion can occur if a user queries a bucket using the `!=` comparator. This will result in PHP's call stack limit exceeding, and/or increased memory consumption, potentially leading to a denial of service. Version 1.0.0 contains a patch for the issue.

Summary		(es) Bucket es una extensión de MediaWiki para almacenar y recuperar datos estructurados en artículos. Antes de la versión 1.0.0, puede ocurrir una recursión infinita si un usuario consulta un bucket usando el comparador '!='. Esto resultará en la superación del límite de la pila de llamadas de PHP y/o un aumento del consumo de memoria, lo que podría llevar a una denegación de servicio. La versión 1.0.0 contiene un parche para el problema.
