      "value": "The typo3/html-sanitizer package is an HTML sanitizer, written in PHP, aiming to provide XSS-safe markup based on explicitly allowed tags, attributes and values. Due to a parsing issue in the upstream package `masterminds/html5`, malicious markup used in a sequence with special HTML comments cannot be filtered and sanitized. This allows for a bypass of the cross-site scripting mechanism of `typo3/html-sanitizer`. This issue has been addressed in versions 1.0.7 and 2.0.16 of the `typo3/html-sanitizer` package. Users are advised to upgrade. There are no known workarounds for this issue."

Debido a un problema de an\u00e1lisis en el paquete upstream \"masterminds/html5\", el marcado malicioso usado en una secuencia con comentarios HTML especiales no puede ser filtrado y saneado. Esto permite omitir el mecanismo de tipo cross-site scripting de \"typo3/html-sanitizer\". Este problema ha sido abordado en versiones 1.0.7 y 2.0.16 del paquete \"typo3/html-sanitizer\". Es recomendado a usuarios actualizar. No se presentan mitigaciones conocidas para este problema"
