CVE-2026-32820
dataCycle Public Markdown Path Traversal Via /docs/*path
Description
dataCycle is a data management system for centrally storing, managing, searching, finding, and distributing data. In dataCycle-CORE, the module handling core processing and framework rules, before and including version 25.07.3, the documentation and static markdown renderer accepts attacker-controlled path segments and only runs them through the Rails HTML sanitizer, which does not remove directory traversal sequences. An unauthenticated attacker can traverse out of the intended `docs` or `static` directories and render arbitrary `.md` files from the application root or engine root. This is patched in version 26.06.08.

Action Type Old Value New Value Added Translation Title: dataCycle-CORE de datacycle-engine, Description: dataCycle es un sistema de gestión de datos para almacenar, gestionar, buscar, encontrar y distribuir datos de forma centralizada. En dataCycle-CORE, el módulo que gestiona el procesamiento central y las reglas del framework, antes e incluyendo la versión 25.07.3, el renderizador de documentación y markdown estático acepta segmentos de ruta controlados por el atacante y solo los procesa a través del saneador HTML de Rails, que no elimina secuencias de salto de directorio. Un atacante no autenticado puede salir de los directorios previstos ’docs’ o ’static’ y renderizar archivos ’.md’ arbitrarios desde la raíz de la aplicación o la raíz del motor. Esto está parcheado en la versión 26.06.08. -
