CVE-2026-61743

Estado: AplazadaMedia (6.3)—

Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. Prior to 5.2.2, Chartbrew's server/modules/safeRequest.js calls validateOutboundUrl() to resolve and validate a target hostname, but request-promise performs a separate DNS resolution for the actual connection. An authenticated user who can create or test API connections and controls the target DNS name can return a public address during validation and a private address during the request, bypassing the protections implemented by server/modules/outboundTargetPolicy.js. This DNS rebinding condition can expose internal services, localhost resources, or cloud metadata endpoints. This issue is fixed in version 5.2.2.

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.

Usuario autenticado explota DNS rebinding en request-promise para acceder a servicios internos/metadata cloud (AV:N, PR:L); acceso a credenciales o datos internos expuestos mediante SSRF implícito y lectura de información local.

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.
