Impacto secundarioT1195.001 Compromise Software Dependencies and Development Toolsinitial access75 %

Vector CVSS con UI:A (requiere interacción del usuario) indica explotación en el cliente (T1203). El atacante distribuye un plugin de Helm sin firma válida que se instala igualmente, violando la verificación de provenance (T1553.006). Afecta también la cadena de suministro del software (T1195.001).

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.
