By crafting malicious XML content that exploits inefficient regular expression complexity used in the parsing process, an attacker can cause a denial-of-service (DoS) condition. This vulnerability allows for the system to hang and consume significant resources, potentially rendering services that utilize Scrapy for XML processing unresponsive."}, {"lang": "es", "value": "Se descubri\u00f3 que partes de la API Scrapy eran vulnerables a un ataque ReDoS.
