A stored cross-site scripting vulnerability in the Geomap panel's MapLibre base layer allows a user with the Editor role to execute arbitrary JavaScript in another user's session by hosting a malicious style configuration, enabling escalation to Org Admin.

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

XSS almacenado en panel Geomap (CWE-79) permite inyectar JavaScript arbitrario en sesiones de otros usuarios con rol Editor. Requiere interacción del usuario víctima (UI:R) para visualizar la configuración maliciosa, resultando en ejecución de scripts y escalada a Org Admin.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
