CVE-2026-95376

Estado: AnalizadaAlta (8)—

Externally controlled reference in DevTools in Google Chrome prior to 154.0.8037.57 allowed an adjacent attacker leveraging social engineering to bypass system access restrictions via crafted network traffic. (Chromium security severity: Medium)

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.

Requiere interacción del usuario (UI:R) mediante ingeniería social con tráfico malicioso. Impacto: escalada de privilegios (bypass de restricciones de acceso) y suplantación de identidad (social engineering).

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.
