CVE-2020-4050
En las versiones afectadas de WordPress, el uso incorrecto del valor de retorno del filtro "set-screen-option", permite que campos meta arbitrarios del usuario sean guardados. Requiere que un administrador instale un plugin que pueda usar incorrectamente el filtro. Una vez instalado, pueden ser aprovechados por los usuarios con poco privilegiados. 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:H/PR:L/UI:N/S:U/C:N/I:L/A:N
- Puntuación base: 3.1
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 1.41%
- Percentil entre todas las CVEs puntuadas: 72
