CVE-2026-57578

Estado: AplazadaCrítica (9.2)—

DotVVM is an open source MVVM framework for web applications. Prior to 4.2.11, 4.3.15, and 5.0.0-preview09-final, AuthorizeActionFilter performs no authorization because its explicit ICommandActionFilter.OnCommandExecutingAsync, IViewModelActionFilter.OnViewModelCreatedAsync, and IPresenterActionFilter.OnPresenterExecutingAsync implementations return completed tasks instead of invoking the corresponding checks. Applications relying on this filter can therefore expose protected commands, view models, or presenters to unauthorized requests without any special bypass technique. AuthorizeAttribute correctly implements the same interfaces and can be used as a workaround. This issue is fixed in versions 4.2.11, 4.3.15, and 5.0.0-preview09-final.

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 sin autenticación permite acceso a comandos/presentadores protegidos; AuthorizeActionFilter no valida, exponiendo recursos sin autenticación requerida.

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.
