CVE-2022-28284

Estado: ModificadaAlta (8.8)—

El elemento <code></code> de SVG podría haberse utilizado para cargar contenido inesperado que podría haber ejecutado un script en determinadas circunstancias. Si bien la especificación parece permitir esto, otros navegadores no lo hacen, y los desarrolladores web confiaron en esta propiedad para la seguridad de los scripts, por lo que la implementación de gecko estaba alineada con la de ellos. Esta vulnerabilidad afecta a Firefox &lt; 99.

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).
