CVE-2026-71314
Nuxt is an open-source web development framework for Vue.js. From 3.1.0 until 3.21.10 and 4.5.1, an unauthenticated attacker can use a server island v-for prop, including vforToArray and , to trigger unbounded SSR memory allocation until MAX_VFOR_LENGTH = 100000 and crash the Nuxt process. This issue is fixed in 3.21.10 and 4.5.1.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

🎯 Técnicas ATT&CK
Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
- Explotación
T1190Exploit Public-Facing Applicationinitial access85 % - Impacto principal
T1499.004Application or System Exploitationimpact90 % - Impacto secundario
T1499Endpoint Denial of Serviceimpact75 %
Vector CVSS AV:N/AC:L/PR:N/UI:N indica explotación remota sin autenticación (T1190). El atacante causa DoS mediante asignación ilimitada de memoria en SSR hasta agotar recursos y crashear el proceso (T1499.004 - resource exhaustion). CWE-400 (sin límites de recursos) y CWE-789 (asignación ilimitada
Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
