CVE-2026-78299

Estado: Pendiente de análisisCrítica (9.1)—

In Eclipse Embedded CDT versions 6.0 to 6.7 if the CMSIS-Pack archive extracts a compromised CMSIS pack the archive extraction can extract files to locations outside of the pack, allowing writing of arbitrary files to other locations on disk.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
Puntuación base: 9.1

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.54%
Percentil entre todas las CVEs puntuadas: 43
Fecha de la puntuación: 5/10/2026

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).
