CVE-2026-25227

Estado: AnalizadaAlta (7.2)—

authentik is an open-source identity provider. From 2021.3.1 to before 2025.8.6, 2025.10.4, and 2025.12.4, when using delegated permissions, a User that has the permission Can view * Property Mapping or Can view Expression Policy is able to execute arbitrary code within the authentik server container through the test endpoint, which is intended to preview how a property mapping/policy works. authentik 2025.8.6, 2025.10.4, and 2025.12.4 fix this 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/PR:H: acceso remoto con privilegios (Can view Property Mapping/Expression Policy) sobre servicio, típico T1210. Ejecución arbitraria de código en el contenedor (test endpoint) = T1059. Potencial escalada si el contenedor tiene privilegios = T1068.

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.
