CVE-2025-42873

SAPUI5 (and OpenUI5) packages use outdated 3rd party libraries with known security vulnerabilities. When markdown-it encounters special malformed input, it fails to terminate properly, resulting in an infinite loop. This Denial of Service via infinite loop causes high CPU usage and system unresponsiveness due to a blocked processing thread. This vulnerability has no impact on confidentiality or integrity but has a high impact on system availability.

Summary		(es) Los paquetes SAPUI5 (y OpenUI5) utilizan bibliotecas de terceros obsoletas con vulnerabilidades de seguridad conocidas. Cuando markdown-it encuentra una entrada malformada especial, no logra terminar correctamente, lo que resulta en un bucle infinito. Esta denegación de servicio a través de un bucle infinito causa un alto uso de CPU e inoperatividad del sistema debido a un hilo de procesamiento bloqueado. Esta vulnerabilidad no tiene impacto en la confidencialidad o integridad, pero tiene un alto impacto en la disponibilidad del sistema.
