CVE-2026-1774

Estado: AplazadaCrítica (9.8)—

CASL Ability, versions 2.4.0 through 6.7.4, contains a prototype pollution vulnerability.

CVSS

Probabilidad de explotación (EPSS)

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.

Vector CVSS AV:N/PR:N/UI:N indica explotación remota sin autenticación (T1190). Prototype pollution permite inyectar código o modificar flujo, causando ejecución de código (T1059), manipulación de datos (T1565) y acceso a información (T1005).

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.
