CVE-2012-5851
Estado: ModificadaMedia (4.3)—💥 Exploit
html/parser/XSSAuditor.cpp in WebCore in WebKit, as used in Google Chrome through 22 and Safari 5.1.7, does not consider all possible output contexts of reflected data, which makes it easier for remote attackers to bypass a cross-site scripting (XSS) protection mechanism via a crafted string, aka rdar problem 12019108.
CVSS
- Versión: 2.0
- Vector: AV:N/AC:M/Au:N/C:N/I:P/A:N
- Puntuación base: 4.3
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 2.28%
- Percentil entre todas las CVEs puntuadas: 83
- Fecha de la puntuación: 7/10/2026
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).
💥 Exploits públicos
Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
