CVE-2026-94574

Estado: AplazadaAlta (7.8)—

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

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.

Vulnerabilidad local en ruta de configuración predecible y escribible por usuarios sin privilegios (C:\msys64), permitiendo escalada de privilegios ejecutando código arbitrario mediante use_askpass.

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.
