CVE-2026-94212

Estado: AplazadaMedia (6.4)—

Improper verification of cryptographic signature vulnerability in Apache APISIX.

Any unauthenticated attacker could impersonate any user on every route protected by the saml-auth plugin under default configuration. This issue affects Apache APISIX: from 3.17.0 through 3.18.0.

Users are recommended to upgrade to version 3.19.0, which fixes the issue.

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.

AV:N con PR:L permite explotar servicio remoto (T1210). Impersonación de usuarios (T1078) por falta de verificación criptográfica en SAML; acceso con credenciales falsas (T1550.001) en rutas protegidas.

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.
