CVE-2026-93315

Estado: Pendiente de análisisMedia (5.8)—

Cuando está habilitada la red de proxy con inyección de CA, una compilación puede modificar su paquete de CA antes de la limpieza. Esto puede hacer que la limpieza se bloquee, opere fuera del sistema de archivos raíz (rootfs) de la compilación o falle sin que falle la compilación.

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.

Inferido por reglas deterministas a partir del vector CVSS y la CWE. Solo orientativo.
