FKIE_CVE-2026-25870

Vulnerability from fkie_nvd - Published: 2026-02-10 23:16 - Updated: 2026-04-15 00:35
Severity
5.8 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N
Summary
DoraCMS version 3.1 and prior contains a server-side request forgery (SSRF) vulnerability in its UEditor remote image fetch functionality. The application accepts user-supplied URLs and performs server-side HTTP or HTTPS requests without sufficient validation or destination restrictions. The implementation does not enforce allowlists, block internal or private IP address ranges, or apply request timeouts or response size limits. An attacker can abuse this behavior to induce the server to issue outbound requests to arbitrary hosts, including internal network resources, potentially enabling internal network scanning and denial of service through resource exhaustion.

La aplicaci\u00f3n acepta URLs proporcionadas por el usuario y realiza peticiones HTTP o HTTPS del lado del servidor sin validaci\u00f3n suficiente o restricciones de destino. La implementaci\u00f3n no aplica listas de permitidos, bloquea rangos de direcci\u00f3n IP internas o privadas, ni aplica tiempos de espera de petici\u00f3n o l\u00edmites de tama\u00f1o de respuesta. Un atacante puede abusar de este comportamiento para inducir al servidor a emitir peticiones salientes a hosts arbitrarios, incluyendo recursos de red internos, lo que podr\u00eda permitir el escaneo de red interno y la denegaci\u00f3n de servicio por agotamiento de recursos."
