CVE-2026-103267

Estado: AplazadaMedia (5.3)—

Ghost versions before 6.62.0 contain an authentication bypass vulnerability in staff invite acceptance that allows users to specify any email address when creating their account. Attackers can accept leaked invite tokens with attacker-controlled email addresses, or legitimate recipients can register with unintended email providers.

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.

Bypassing authentication en servicio remoto (Ghost) con PR:L (privilegio bajo) mediante tokens leaked. Permite crear cuentas no autorizadas (T1078.001, T1098.001) e impersonar usuarios legítimos (T1556.001).

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.
