CVE-2026-41895

changedetection.io is a free open source web page change detection tool. In 0.54.9 and earlier, xpath_filter() switches to XML mode for XML/RSS content and creates etree.XMLParser(strip_cdata=False) without explicitly disabling external entity resolution, external DTD loading, or network-backed entity lookup. The helper then parses untrusted XML bytes directly with etree.fromstring(...).

Summary		(es) changedetection.io es una herramienta gratuita de código abierto para la detección de cambios en páginas web. En 0.54.9 y versiones anteriores, xpath_filter() cambia al modo XML para contenido XML/RSS y crea etree.XMLParser(strip_cdata=False) sin deshabilitar explícitamente la resolución de entidades externas, la carga de DTD externas o la búsqueda de entidades respaldadas por la red. El asistente luego analiza bytes XML no confiables directamente con etree.fromstring(...).
