CVE-2026-26130
Estado: ModificadaAlta (7.5)—
Allocation of resources without limits or throttling in ASP.NET Core allows an unauthorized attacker to deny service over a network.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
- Puntuación base: 7.5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 2.44%
- Percentil entre todas las CVEs puntuadas: 84
- Fecha de la puntuación: 6/10/2026
EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
🎯 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 access92 % - Impacto principal
T1499.004Application or System Exploitationimpact85 %
Vector CVSS AV:N/AC:L/PR:N/UI:N indica explotación remota sin autenticación (T1190). CWE-770 y descripción de asignación sin límites confirman DoS por agotamiento de recursos (T1499.004).
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.
