CVE-2026-55229

Estado: AplazadaAlta (7.5)—

Gotenberg is a Docker-powered stateless API for PDF files. Prior to 8.34.0, Gotenberg's /forms/libreoffice/convert endpoint allows a specially crafted document to cause LibreOffice to automatically retrieve external HTTP(S) resources and local file resources during document conversion, enabling blind SSRF and limited local file disclosure via linked image resource loading. This issue is fixed in version 8.34.0.

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.

Vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N indica exposición remota sin autenticación ni interacción (T1190). El texto describe SSRF (T1090) y disclosure de archivos locales (T1005) mediante carga de recursos HTTP(S) y locales en conversión de documentos.

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.
