CVE-2026-94574
A local cross-user code execution vulnerability exists in GNU wget (Windows builds from eternallybored.org) due to a hardcoded configuration file path (C:\msys64) that is writable by unprivileged users, allowing for arbitrary code execution via the use_askpass directive, potentially allowing local privilege escalation.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
- Puntuación base: 7.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.12%
- Percentil entre todas las CVEs puntuadas: 2
- Fecha de la puntuación: 6/10/2026
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).
