CVE-2026-68578

ArcadeDB versions before 26.7.3 fail to bind the authenticated principal in the MCP HTTP transport, causing all engine permission checks to silently pass as no-ops. Non-root MCP-allowed users can perform arbitrary database writes, DDL, schema mutations, and execute arbitrary JavaScript code via the query tool.

Summary		(es) Versiones de ArcadeDB anteriores a la 26.7.3 fallan al vincular el principal autenticado en el transporte HTTP de MCP, lo que provoca que todas las comprobaciones de permisos del motor pasen silenciosamente como no-ops. Usuarios no-root permitidos por MCP pueden realizar escrituras arbitrarias en la base de datos, DDL, mutaciones de esquema y ejecutar código JavaScript arbitrario a través de la herramienta de consulta.
