An address bar spoofing issue in affected versions of Arc could allow an attacker to spoof the browser address bar via a <select> element that triggers requestFullscreen without displaying the fullscreen notification.

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) para que ejecute una acción en navegador (select/fullscreen). El spoofing de barra de direcciones facilita phishing y suplantación de identidad del sitio, con impacto de integridad (I:H) sin privilegios previos (PR:N).

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.
