Estado: ModificadaMedia (4.3)—💥 Exploit

Multiple cross-site scripting (XSS) vulnerabilities in index.php in the ProofReader (com_proofreader) component 1.0 RC9 and earlier for Joomla! allow remote attackers to inject arbitrary web script or HTML via the URI, which is not properly handled in (1) 404 or (2) error pages.

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).

💥 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.
