CVE-2026-34054

Estado: Pendiente de análisisAlta (7.8)—

vcpkg is a free and open-source C/C++ package manager. Prior to version 3.6.1#3, vcpkg's Windows builds of OpenSSL set openssldir to a path on the build machine, making that path be attackable later on customer machines. This issue has been patched in version 3.6.1#3.

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.

AV:L, PR:L, sin UI: escalada de privilegios local. Ruta openssldir en máquina de compilación permite manipular dependencias (T1574.007) y ejecutar código arbitrario.

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.
