      "value": "PhpWeasyPrint is a PHP library allowing PDF generation from a URL or an HTML page. Prior to version 2.6.0, `AbstractGenerator::$temporaryFiles` is a public array, and `removeTemporaryFiles()` — invoked from `__destruct()` and from a registered shutdown function — calls `unlink()` on every entry without verifying that the path is contained within the temporary folder. Any code holding a reference to a generator instance can push an arbitrary path into the array and have it deleted on script shutdown. This mirrors the KnpLabs/snappy issue GHSA-87qc-37cw-84h4. PhpWeasyPrint version 2.6.0 contains a patch for the issue."

Antes de la versión 2.6.0, ’AbstractGenerator::$temporaryFiles’ es un array público, y ’removeTemporaryFiles()’ - invocado desde ’__destruct()’ y desde una función de apagado registrada - llama a ’unlink()’ en cada entrada sin verificar que la ruta esté contenida dentro de la carpeta temporal. Cualquier código que mantenga una referencia a una instancia de generador puede insertar una ruta arbitraria en el array y hacer que se elimine al finalizar el script. Esto refleja el problema de KnpLabs/snappy GHSA-87qc-37cw-84h4. PhpWeasyPrint versión 2.6.0 contiene un parche para el problema."
