CVE-2026-27741

Estado: AnalizadaMedia (5.1)—

Bludit version 3.16.1 contains a cross-site request forgery (CSRF) vulnerability in the /admin/uninstall-plugin/ and /admin/install-theme/ endpoints. The application does not implement anti-CSRF tokens or other request origin validation mechanisms for these administrative actions. An attacker can induce an authenticated administrator to visit a malicious page that silently submits crafted requests, resulting in unauthorized plugin uninstallation or theme installation. This may lead to loss of functionality, execution of untrusted code via malicious themes, and compromise of system integrity.

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).

Un atacante puede inducir a un administrador autenticado a visitar una página maliciosa que envía silenciosamente peticiones manipuladas, lo que resulta en la desinstalación no autorizada de un plugin o la instalación de un tema. Esto puede llevar a la pérdida de funcionalidad, la ejecución de código no confiable a través de temas maliciosos y el compromiso de la integridad del sistema."
