In versions 5.0.9 through 5.3.3, a RangeError vulnerability exists in the numeric entity processing of fast-xml-parser when parsing XML with out-of-range entity code points (e.g., `�` or `�`). This causes the parser to throw an uncaught exception, crashing any application that processes untrusted XML input. Version 5.3.4 fixes the issue."},{"lang":"es","value":"fast-xml-parser permite a los usuarios validar XML, analizar XML a objeto JS o construir XML desde objeto JS sin librerías basadas en C/C++ y sin callback. En las versiones 4.3.6 a la 5.3.3, existe una vulnerabilidad de tipo RangeError en el procesamiento de entidades numéricas de fast-xml-parser al analizar XML con puntos de código de entidad fuera de rango (p. ej., '?' o '?'). Esto provoca que el analizador lance una excepción no capturada, lo que bloquea cualquier aplicación que procesa entrada XML no confiable.
