Estado: AplazadaAlta (8.7)—

WordPress Time Capsule Plugin 1.21.16 contains an authentication bypass vulnerability that allows unauthenticated attackers to gain administrative access by sending a crafted POST request with the IWP_JSON_PREFIX header. Attackers can exploit this flaw to obtain valid administrator session cookies and access the WordPress dashboard without providing credentials.

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.

AV:N/PR:N/UI:N indica red sin autenticación. CWE-288 es autenticación débil. Descripción explícita: bypassing auth para acceso administrativo = T1190 + T1078 (obtención de sesión válida). T1098 secundario por manipulación de cuentas administrativas.

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.
