CVE-2020-4049
Estado: ModificadaBaja (2.4)—
En las versiones afectadas de WordPress, cuando se cargan temas, el nombre de la carpeta temas puede ser diseñada en una manera que podría conllevar a una ejecución de JavaScript en /wp-admin en la página temas. Esto requiere un administrador para cargar el tema, y ??es un ataque de tipo self-XSS de baja gravedad. 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:H/UI:R/S:U/C:N/I:L/A:N
- Puntuación base: 2.4
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 2.53%
- Percentil entre todas las CVEs puntuadas: 84
- 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).
