CVE-2026-80465

Estado: AplazadaAlta (8.8)—

A vulnerability has been identified in Mendix SAML (Mendix 10 compatible) (All versions < V4.2.3), Mendix SAML (Mendix 11 compatible) (All versions < V4.2.3), Mendix SAML (Mendix 9.24 compatible) (All versions < V3.6.27). Affected versions of the module do not properly validate the SAML response signature. This could allow unauthenticated remote attackers to hijack an account (session) in specific SSO configurations.

CVSS

Vector: CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:H/VI:H/VA:N/SC:H/SI:H/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X
Puntuación base: 8.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.28%
Percentil entre todas las CVEs puntuadas: 18
Fecha de la puntuación: 6/10/2026

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).

🎯 Técnicas ATT&CK

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

ExplotaciónT1203 Exploitation for Client Executionexecution70 %
Impacto principalT1078.004 Cloud Accountsstealth · persistence · privilege escalation · initial access75 %
Impacto secundarioT1556.003 Pluggable Authentication Modulesdefense impairment · persistence · credential access65 %

Vector CVSS con UI:P (interacción del usuario) indica T1203. Falta de validación de firma SAML permite suplantación de identidad y acceso a cuentas (T1078.004). Ataque SSO sugiere manipulación de autenticación (T1556.003).

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.
