CVE-2026-30247

Estado: AnalizadaAlta (7.5)—

WeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval. Prior to version 0.2.12, the application's "Import document via URL" feature is vulnerable to Server-Side Request Forgery (SSRF) through HTTP redirects. While the backend implements comprehensive URL validation (blocking private IPs, loopback addresses, reserved hostnames, and cloud metadata endpoints), it fails to validate redirect targets. An attacker can bypass all protections by using a redirect chain, forcing the server to access internal services. Additionally, Docker-specific internal addresses like host.docker.internal are not blocked. This issue has been patched in version 0.2.12.

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.

SSRF en endpoint público sin autenticación (AV:N/AC:L/PR:N). Impacto primario T1090 (proxy/SSRF para acceder servicios internos). Secundario T1005: lectura de datos internos accesibles desde el servidor.

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.

Antes de la versión 0.2.12, la característica 'Importar documento vía URL' de la aplicación es vulnerable a la falsificación de petición del lado del servidor (SSRF) a través de redirecciones HTTP. Aunque el backend implementa una validación exhaustiva de URL (bloqueando IPs privadas, direcciones de bucle invertido, nombres de host reservados y puntos finales de metadatos en la nube), no logra validar los objetivos de redirección. Un atacante puede eludir todas las protecciones mediante el uso de una cadena de redirección, forzando al servidor a acceder a servicios internos. Además, las direcciones internas específicas de Docker como host.docker.internal no están bloqueadas. Este problema ha sido parcheado en la versión 0.2.12."
