CVE-2026-48612

Estado: AplazadaAlta (8)—

Improper state verification in the OAuth implementation could allow an attacker to manipulate the authentication flow and cause a victim’s account to be linked to an attacker-controlled account. This can result in unauthorized account linking and potential account takeover.

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.

UI:R indica interacción del usuario (clickear enlace OAuth malicioso). El ataque manipula el flujo OAuth para vincular cuentas ajenas: T1098.002 (modificación de credenciales/sesión) y T1556 (toma de control de cuenta).

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.
