CVE-2026-24885

Estado: AnalizadaAlta (8)—

Kanboard is project management software focused on Kanban methodology. Prior to 1.2.50, a Cross-Site Request Forgery (CSRF) vulnerability exists in the ProjectPermissionController within the Kanboard application. The application fails to strictly enforce the application/json Content-Type for the changeUserRole action. Although the request body is JSON, the server accepts text/plain, allowing an attacker to craft a malicious form using the text/plain attribute. Which allows unauthorized modification of project user roles if an authenticated admin visits a malicious site This vulnerability is fixed in 1.2.50.

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.

CSRF con UI:R requiere interacción del usuario (admin visita sitio malicioso). El impacto es modificación de roles de usuario (T1185: válido para manipulación de cuentas). T1098 secundario: cambio de permisos/roles equivale a modificación de cuentas.

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.
