CVE-2026-88897

Estado: AplazadaAlta (8.2)—

Flextype CMS through 1.0.0-alpha.3 accepts API authentication credentials through URL query string parameters in REST API routes. Attackers with access to web server, proxy, or monitoring logs can recover valid API token pairs that grant full API access.

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.

Credenciales de API en parámetros URL expuestos en logs de servidor/proxy (CWE-598); acceso sin autenticación válida (AV:N, PR:N) permite recuperar tokens y obtener acceso total a la API.

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.
