CVE-2020-4046
Estado: ModificadaMedia (5.4)—
En las versiones afectadas de WordPress, los usuarios con pocos privilegios (como colaboradores y autores) pueden usar el bloque incorporado de determinada manera para inyectar HTML no filtrado en el editor de bloques. Cuando las publicaciones afectadas son vistas por un usuario con mayores privilegios, esto podría conllevar a una ejecución de script en el archivo editor/wp-admin. Esto ha sido parcheado en la versión 5.4.2, junto con todas las versiones afectadas anteriormente por medio de una versión menor (versiones 5.3.4, 5.2.7, 5.1.6, 5.0.10, 4.9.15, 4.8.14, 4.7.18, 4.6.19, 4.5.22, 4.4.23, 4.3.24, 4.2.28, 4.1.31, 4.0.31, 3.9.32, 3.8.34, 3.7.34)
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N
- Puntuación base: 5.4
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 2.13%
- Percentil entre todas las CVEs puntuadas: 81
- Fecha de la puntuación: 8/10/2026
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).
