CVE-2026-104473

Estado: AplazadaMedia (5.1)—

YesWiki before 4.5.3 contains multiple reflected cross-site scripting vulnerabilities that allow remote attackers to inject JavaScript through unsanitized parameters such as incomingurl, id, file, tags, and template. Attackers can lure authenticated or unauthenticated users into opening crafted links to hijack sessions and trigger authenticated requests against backend functionality.

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 reflejado en parámetros (CWE-79, UI:A) permite inyectar JavaScript en navegador (T1189). Posibilita ejecución de código JavaScript (T1059.007) y secuestro de sesiones de usuarios autenticados (T1078).

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.
