CVE-2023-4055

Estado: ModificadaAlta (7.5)—

Cuando se superaba el número de cookies por dominio en `document.cookie`, el tarro de cookies real enviado al host ya no era coherente con el estado de tarro de cookies esperado. Esto podía provocar que se enviasen peticiones en las que faltasen algunas cookies. Esta vulnerabilidad afecta a las versiones anteriores a Firefox 116, Firefox ESR 102.14, y Firefox ESR 115.1.

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).
